35 drive shaft question

[dring]

I am putting a 37 ring and pinion in my 35. I'm wondering if there is any reason not to use the 37 drive shaft instead of my tubular 35? It's the same length and will match the 6 spline pinion. It looks to me like it should work, but was wondering if anyone knows of a reason not to. Thanks.

May start vibrating or whipping without the center bearing .

Sorry for off topic comment, hijack but Can you tell me what holds the speedo drive gear to the tubular shaft if anything? Anyone have a pic

Fairlane500,A snap ring in the grouve on the splines.

dring,David J is correct because the shaft is a solid bar.Maybe you can use a 37 torque tube that has the support bearing.Only thing maybe the raduis rods will not line up on the torque tube.

Have you got the 37 parts 'in-your-hand', yet? Many 37's, if not most, still used the tubular driveshaft and a 10-spline pinion. In any event, if you use a 'solid' driveshaft, you will also need to use the 'center-bearing' torque-tube, as the other posters have indicated.
To Fairlane 500... I've got a 37 tubular driveshaft here, and could get a pict, if you really need it. But, there is no 'majic' here, and Duece Lover covered your question.

I also have a tubular type drive shaft (identical to '35-'36) that came out of a bone stock '37 standard coupe. I also have a torque tube with center bearing that has the radius rod mounting lug welded to the tube in the exact same location as a '35-'36 torque tube.
The original 3.78 gear sets were made in both 6 and 10 spline
pinions. The 10 spline version will drop right in a '35-'36 banjo rear.
So...long story short...you can build up a '35-'36 rear with solid or tubular drive shaft with either a 6 or 10 spline ring and pinion gear set, but you should have a center bearing when using a solid drive shaft.

IF for some reason you need to move the wishbone lug on a torque tube with the support bearing...asuming you don't have the correct one like JM35 is mentioning...

I've just taken a cut off wheel and sliced through the weld around the square base... go slowly as to not cut into the tube much... eventually you'll be able to remove it... grind the tube smooth (weld up any cut marks)

then reweld the lug where ever it needs to fall to match the wishbones your running...

Can a center bearing be placed into an earlier torque tube?

funny, i have the torque tube set up on my 37 with no center carrier bearing.....so i think every combination has been coveree

Dick Spadaro has a tube drive shaft kit (straight tube) that can be finished to fit any length and any rear spline. As long as it's tubular, you won't need the center damper bearing. These would be an ideal replacement for the old conical tube shafts when they are worn out.

dring, Is your 37 pinion a 6 spline?.From what I am to understand 10 spline was also used in 37 and some 38 commercial applications.I believe that the tubular driveshaft is only 10 spline. Other may chime in on this subject.

PeteVS,To answer your question.Don't believe so.

I would stick with the tube driveshaft. My 37 had a 10 spline on it... I like the tube shafts in my 35's that center bearing can be a headache if it is froze or needs to be replaced. Convert the tube shaft to 6 spline if needed Machine shop charged me $75 to do so..
