fparsons, I forgot to mention in my last post, if you want to use a solid drive shaft and a 6 to 6 coupling you would need to think about using a later type torque tube with center bearing. Otherwise, that solid shaft will whip and vibrate in a stock '35 torque tube.

fparsons, I will be doing the same thing on one of my '35's. I have both 3.78 and 3.54 gear sets and both have 10 spline pinions. I can't decide which set I should use. I'm not doing all flat road driving here in MD so right now I'm thinking the 3.78's would be my best choice. If you could find a set of 3.78 gears with 10 spline pinion you would not have to modify your drive shaft. I do know of a drive shaft shop in WV that can do a first class job of welding a 6 spine end in a '35 hollow type drive shaft. A friend had his done there and they did a beautiful job. I'll attempt to post a picture here. Let me know if you would like their address. Good luck on your conversion.

There were two drive shafts used between '35 and '41. The hollow 10 spline was used from '35 to '38. The solid, six spline shaft was used between '37 and '41. We use the 10 to 6 spline adapter and weld it to the driveshaft. I doubt you will find a 6 spine shaft to fit your '35. Last year we adapted a couple of hollow shafts for a customer in Nebraska after a local shop scr*w*d one up. There is no advantage of one type over another that I know of.

Thanks for the timely advice ...I have a 3:78 so thought I would give it a shot ...seems the 3:54 would be great, but since I have the 3:78 in good shape I will use it until I come across a 3:54 in my area ...

To answer your question more information is required from you. What year car or differential are you talking about? Which type drive shaft do you have? Closed vs. open? Solid vs. hollow inner shaft. Also, on your 3.78 gear se t, does the pinion gear have 6 or 10 splines?
