'41 PU Rear Window
 

My recently acquired '41 truck has a slide-opening rear window. I don't believe these were a factory option when new...or were they?

A picture is worth a thousand guesses

Ford never installed a sliding rear window in a '41 pickup.

BS Ford did have a sliding rear window in a 41 truck, more prevalent in canada than in us but they were offered. have on in my 41

Page 43 of the V-8 Club's '40-'41 pickup book has the full details on the sliding rear window. There were two types and the windows carried through the '47 year.

What's the glass bug look like on the sliding glass window?

Re: '41 PU Rear Window
 

One thing they didn't have were those stainless screws and cup washers through the carboard panels.

FOAmerica 46 & 47 trucks had a factory option, so did FOC, Mercury was stock

Re: '41 PU Rear Window
 

The Canadian 38 Ford Truck brochure shows a sliding rear window in the accessories section: https://oldcarbrochures.org/Canada/F...Cdn-28-29.html

You can also see two pictures with the sliding rear window shown in the 46 Mercury brochure: https://oldcarbrochures.org/Canada/F...Trucks-04.html


What I don't understand is why our neighbors in the frozen north needed more ventilation than the folks baking in the southern heat!

Re: '41 PU Rear Window
 

I don't have the specifics for the 1941 back glass bugs but I can tell you that for 1935-1936 trucks, the Ford oval was 1" wide and 0.56" tall. The oval on the doors and windshield glass is 0.69" c 0.44". Not sure why the rear glass received a larger logo but I've confirmed this with Ford Engineering drawings and several original trucks. Attached is a drawing showing the locations on the glass and the dimensions.
The sliding rear window used two identical glass pieces with the logo installed as shown in the illustration. This results in the logo reading properly on the right hand glass when viewed from the back of the truck and reads correctly from inside the truck on the left hand side (at least that's the way it was supposed to be done during production).
All this info is from the mid-1930's but probably didn't change before WW2..

As I understand it, the sliding rear window was an option, but not very common.
The interior light on the other hand wasn't an option on the 41 to the best of my knowledge.
Bob Drake has a sliding rear window kit.

Re: '41 PU Rear Window
 

Interior light was an option in 46 & 47.
The rear window conversion is more complicated than i thought, i have a B Drake sliding rear window, may not install it as it would require removing some window metal/posts, etc. If i cut those out & then window installation becomes a problem, there may be no turning back, I am disappointed in myself to learn it is not that easy......

Re: '41 PU Rear Window
 

Agreed on the Bob Drake window installation. I was thinking of doing it until I saw it required modifying the cab.

Re: '41 PU Rear Window
 

We are on the same page, optional sliding window would be great BUT modifications like that could go South quickly. I am going to leave that one out.....
Thanks.

Re: '41 PU Rear Window
 

wait till you are driving down the road in HOT july in the south you will appreciate the sliding rear window

Re: '41 PU Rear Window
 

Alan,
I cant argue that BUT cutting metal around that window frame is dicey....Matching new parts to old parts is a crap shoot!!

Re: '41 PU Rear Window
 

Is someone willing to show a few pictures of the metal that would need to be cut or trimmed? I'm only familiar with the 1935-39 rear window opening and it would be interesting to see the difference.

Re: '41 PU Rear Window
 

Sorry, I can't, I have already installed my non sliding window & moved on....as i recall when the opening was ready there was a vertical brace on both sides of the window that would have needed to be cut out so the sliders could then move out of the opening. I don't remember if it was just those 2 pieces or not, as i said if i would have cut those out, then continued with Bob Drake installation instructions & found something else as a problem I might have faced reinstalling those 2 pieces, was not willing to got here, I am trying to install as many Period Correct options of 1947, was disappointed to not get this one done.....

Re: '41 PU Rear Window
 

No problem. I was just curious. On my sliding rear window the glass pains both slide inward, not outward. All that was needed was a clear opening, the same size and shape as the one-piece unit.

Re: '41 PU Rear Window
 

drill out a couple of spot welds--will look to see if I have the ones that came out of another cab we put window in

Re: '41 PU Rear Window
 

I bought one for my 41, my question is what does the outside of the window look like, the kit from Drake comes with a nice trim strip for the inside but i don't see anything for the outside. Did they have trouble with air or rain leaking in? I assumed it would use the rubber molding but that isn't the case. Does the window lay against the cab window seam? what keeps rain from getting in? I would love to see a closeup picture of a Drake window installed if anyone has one? Thanks Ron

Re: '41 PU Rear Window
 

The rear window glass should have setting tape applied to the edge. The tape should be wide enough to go up the glass about 1/4" on each side. The tape provides the rain seal on the cab sheet metal. Ford used this technique on windshields before the advent of rubber gaskets. Attached is an image of a windshield cross section just to show how the tape wraps around the glass. The same principle applies to the rear window glass.

Re: '41 PU Rear Window
 

The cross section doesn't look like what I got from Drake to work with. But in any case the outside of the window is going to look unfinished. I don't see any way the Bob Drake kit doesn't allow for leaking inside the cab. Pretty disappointing. Am I missing something?
