The Ford Barn

36tudordeluxe · 04-01-2013, 12:53 AM

I know there have been many Ford 8"'s put in the '35-'40 coupes, but am wondering about the Ford 8" offset interfering with the longer tudor driveshaft tunnel; is this going to be a problem?

I think the floors and tunnels are the same for coupes and sedans.

It is going to be "close". Depending on how exact your body fits the chassis (frame), and exactly where the spring perches are set on the springs, the pinion yoke will be closer to the tunnel on one side.

On my 36 coupe, without a pannard bar, in hard right turns under acceleration the yoke would do a woodpecker by just bearely nicking the tunnel. A BMFH made the spacing just big enough to clear the yoke.

The universal joints tollerate the offset with no problem, What is critical is that the trans yoke and the differential yoke are parallel. Not usually a probem horizontally but make sure the spring perches and shackle lengths keep them aligned vertically.

Did this set up in a '36 sedan. Could be a problem if you tried to dump the rear very low. But, a normal ride height is no problem.

Thanks everyone for responding, am using a CE rear end kit and have no plans at this point to lower the rear any more than what is provided with the CE kit.

I have a 9" in my '40 using a Chassis Engineering Inc. rear suspension system. The banjo is centered so the pinion is offset just under 1", but there are no floor/tunnel to the 3 1/2" drive shaft clearance issues with the axle fully bottomed against stock '40 axle bumpers. My design ride height is 3- 3 1/2" between the bumpers and axle.

Ordered new floor pans about 15 years ago from Bradely & I thought there was a difference in the length between coupe and sedan but can't remember for sure.

The CE kit is what I used in my sedan. As I recall, I drilled new holes in the bottom plates in order to better center the axle in the center of the wheel well. Also, you may have to use shims to adjust the pinion angle.

Can you get 5 on 5 1/2 axles for the 8' rear. I knosw the explorer had them but they are getting hard to find.

Do all 8" rear ends have the offset pinion? I've never worked with anything but 9" ones and there were both available (either pinion yoke centered or offset 2"). I think with the 9" units, the pinions were centered if used in cars and offset if used in trucks and vans. Can you not get an 8" with centered pinion?
