I have reviewed enough of your posts to realize that you have a 48 GMC 1/2-ton truck. It should have a full length torque-tube that goes from the ball and socket joint at the rear of the transmission to the rear axle - in one piece. So, I don't understand the picture you posted of the "collar". Unless it is a long wheelbase 1/2-ton. I don't have any experience with them. It looks like a slip joint in a 2-piece driveshaft. What is mounted at that crossmember?
