I have a 39 3 speed and 39 banjo rear in my 31 Roadster. I want to keep the torque tube closed drive line. Got a few questions if you can help. 1. To measure for the driveshaft, how far does it need to extend into the end of the u-joint coupler that connects it to end of tranny? There is a bolt holding one end of the u-joint to the tranny end, then driveshaft slides in the other end. I'm assuming it is supposed to go just to the end of the u-joint spline? Never seen one mounted... 2. When I get the torque tube shortened do I need to try to keep the center bearing? If yes it would seem I would need to shorten the driveshaft and torque tube from both ends as the center of the driveshaft is a little larger diameter same as the splined ends. Is that right? 3. Anybody know a good shop in Dallas area experienced in doing this correctly? I'm guessing I will get lots of blank stares if I just show up at a driveshaft shop.
