39 pedals in a 36 frame
I am trying to figure out how to modify my 1936 frame for 1939 pedals.
I made a template from the 39 frame and I’m not exactly sure where it should line up on the 36 frame since the bolt holes do not line up perfectly with the 39 pedals. Any help is greatly appreciated. |

Re: 39 pedals in a 36 frame
I believe the '39 mounts to the outside of the frame member. Drake pedals come with a template. More posts expected here. Newc

Hey Lindsay .....Here is the PDF for the template that Bob Drake provides. Not sure about a '36, but it has been said that the BOTTOM, REAR hole in bracket is a match for a 1940 frame bracket, for what that's worth. Not sure if that will help you or not.

Perfect that should work, thanks. I had printed off a Bob Drake template years ago but misplaced it. I will try lining up the bottom rear hole as well. Thanks |

Re: 39 pedals in a 36 frame
One hole lines up and you have to drill the other three holes. I clamped the pedal assembly in place and installed the toe plate/floorboard to check the position of the pedal to the slots in the toe plate. That tells you if the pedals are in the correct location. Then drill the holes. The clutch pushrod can be offset or change the lever on the throw out shaft to correct alignment. I just converted my 36 pickup about a year ago, works great.

Re: 39 pedals in a 36 frame
I've done this conversion a few times in the past using the Drake template. It takes a little work with a small grinder and die grinder but it will fit. One thing you'll need is the 39 clutch arm so the linkage will line up.

I do not have a 39 clutch arm, so will have to try find one. (I’ll buy one if anybody has an extra one laying around) Bob Drake no longer lists the brake pedals or 39 clutch arm. Seems like they are fazing things out. |

Re: 39 pedals in a 36 frame
I am in the process of making fabricated 39 clutch arms but because of chassis work in my shop I am several months out. I have made fabricated 35/36 arms for many years.

The 1st picture BELOW shows a '35 chassis which has had a set of '39 pedals adapted to it. This image shows the 1939 clutch arm and how it leans toward the LEFT side of the car to line-up with the '39 pedal. DO NOT think that you can just heat and bend an arm from another year, because the '39 arm is of a specific length (hole to hole center lines), and if not the proper length, will screw-up the ratio of the whole pedal/arm set-up as far as feel and proper clutch disengagement. This 2nd picture BELOW shows the same '35 chassis and the relative position of the '39 pedals, as well as the linkage between pedal and clutch-release arm. Pay no attention to the custom extension for the master cylinder mount. Your replacement transmission mount appears to be the correct '37 thru '40 mount. I would feel comfortable using 5/16" bolts with this mount. BELOW is a '37 thru '40 steering box mount. Those holes APPEAR to be more like 3/8" holes. If so, I would use 3/8" bolts. If the original rivet holes in the chassis are only 5/16", then so be it. DD . |

Re: 39 pedals in a 36 frame
Also note in the photos above that there is a notch in the frame were the clutch pedal arm hits the frame. If your frame doesn't have the notch the clutch pedal will bottom out on the frame and you will not get full travel.

Thanks for the reference pictures. The template I made from 39 frame matched the Drake template. When you suggested using the rear bottom hole, it is very close. It would move the pedals forward 1/2-3/4”. Probably would work fine. I didn’t take the steering box bracket out. The top holes are a bit oval but the bottom are 5/16. I will make the top ones 3/8 and leave the bottom 5/16. I will have to drill new holes for the transmission mount as the spacing is different between the two brackets. It shouldn’t be hard as I will mark a centreline across the frame and install the new one in the same centre line. With the picture showing the turtle, is it installed upside down? Thanks for all the help |

Good catch! That was PeterC's black '35 3-window coupe. His car has a Columbia rear end, and as such, the speedo cable runs toward the right side of the car for the controls hook-up. DD . |

Re: 39 pedals in a 36 frame
I just drilled the steering box plate out of my '36 and bolted the '37 in. Lots of drilling, started with a small bit and worked my way up. I did not have to get under the car. I was able to drill everything from the top. I used 3/8 grade 8 bolts and steel lock nuts. Not sure if I had to, but it makes me feel better.
Back to the pedals, after I installed the '39 pedal assy, and put the interior back together, the gas pedal is right next to the brake pedal. When I put my foot on the brake, I usually hit the gas pedal too. And yes, I do have the gas pedal with the off-set hole and it is still under the brake pedal. I am thinking of a torch and just bending it a bit. Anyone got a better idea?

Re: 39 pedals in a 36 frame
Grade 8 bolts are really designed for forces that apply vertical force. Pull. Not great for shear. That said they are fine for what you are doing.
I wouldn't worry about torch bending the pedal. Just my opinion. They are forged not cast. |

Lindsay noted in post #12 possibly moving the pedal set forward 1/2" to 3/4" or so. With the pedals mounted on that inboard rail, any movement toward the front will also move the pedals to the left, which would likely help your interference situation with the gas pedal to some degree. Although utilizing '39 pedals in a '35-'36 is a very popular swap, I've never heard of anyone declaring it as a "PERFECT" bolt-in swap. This swap rates as a great starting point, with some 'tweaking' necessary to fine-tune the swap for a comfortable result. It is certainly OK to bend the pedals for a custom fit. Be careful though, as many of the '39 CLUTCH pedals are cast iron, which cannot be heated and bent. If the pedal arm is straight and appears in the form of an "I"-beam, it is a cast piece. You should NOT try to heat and bend a cast piece. The picture BELOW shows a '39 pedal set. The clutch pedal is the "I" Beam-looking pedal on the bottom. No heat and bend! DD |

Re: 39 pedals in a 36 frame
I have 39 pedals in my 36. No issues. Respect your opinion.
Moving them forward would change the angle quite a bit over the length of the arm. But a shim might do the same thing. Not that I would on a major component or keep hollowing out a frame. See what pedals you have and assess. Last edited by Tinker; 01-15-2022 at 12:55 AM. |

I FINALLY found this image that shows why the '39 clutch arm is angled off to the left. This is a '39 pedal set in the picture BELOW. Below is a comparison of all the different clutch arms. You can see why the height & angles can make a difference. DD |

Re: 39 pedals in a 36 frame
The bottom photo is my '38 1/2T pickup. I used the Bob Drake template for the location of the '39 pedals. Everything lined up perfectly except the clutch shaft arm. I ended up just making a longer clutch shaft that located the stock clutch arm inline with the clevis on the clutch pedal.

Re: 39 pedals in a 36 frame
Late to the party here, but wanted to thank everyone for the
additional info. ("Fine print"), and great D/D/'s closeups of Peter's beautiful '35 chassis, (LOVE that car!). When I started to mock up this same combo. in my '36 a few years back, I could see it was not going to be the "bolt-in" swap some had mentioned. Now I can see the pedal holes in the Carpenter toe boards are probably not going to align either. Just another little glitch in getting the puzzle pieces to all fit together! |

He has a business and makes kits for changing over to hydraulic brakes. A friend installed one on a 1935 Ford, quite nice- and no mods to the car at all. The business name may be The V8 Garage (corrections most welcome). Karl |

Re: 39 pedals in a 36 frame
I still have lots to do but it is now a roller. Next thing I will do is install the Vern Tardel rear drum retainers and run my brake lines.
After that I will get the body on the rotisserie and clean the underneath and ready the underside for paint. |

Re: 39 pedals in a 36 frame
I made a bit more headway running the brake lines. I had to order some fittings from third GEN. I fabricated two brackets to hold the hose ends to the frame and was able to drill a hole through the inner fenders. I had lots of gravel guard left over so I use some on the brake lines next to the master cylinder.

Re: 39 pedals in a 36 frame
Lindsay, is that the stoplight pressure switch in the front brake circuit? If you lose pressure to the front brakes, you will also lose the signal for your brake lights. You might consider a mechanical brake light switch rather than a pressure switch.

TINKER ....As I originally said, the Ford pedals with an I-beam cross section are "CAST"-iron. As far as "running you down"....I COULD say that you make it easy to do when you continually get your information from WHO KNOWS WHERE, but I am here with hopes of sharing REAL information with those interested in hearing such.

Yes, I’ll probably leave it in the plumbing. I can’t hook,up a mechanical one until the body is back on.
