| | | | Joined: Apr 2001 Posts: 31 Wrench Fetcher | | Wrench Fetcher Joined: Apr 2001 Posts: 31 | I have a 1937 GMC with a 3 speed. I want to swap in a 37 4-speed I have. The 4 speed has a u joint with a speedometer gear. I have already updated the rear to a 41 rear (18 spline) with 3.55 gears. To do this I have to find a u joint that I can switch the torque tube side. I have looked on ebay for a similar 41 1/2 ton u joint without luck. Anybody have experience with this?
