4 Spd driveshaft

It has been forever since I needed this so this is an educated guess. Assuming you have it all in the car I believe that the driveshaft shop is looking for the center point of the universal bearing front to the centerpoint of the universal bearing back. I would just call the shop and make sure you and they argree on what measurement they are expecting to recieve. This is the kind of thing where you only look stupid walking back into the shop with a shaft that they have already worked on and is the wrong lenght.
