Had my 4 peed car on the lift taking things apart and noticed that the drive shaft in this car is not the same as any of the others. The front section is the same as my other 4 speed front section. This back section is the smaller diameter but this one was not made with the rubber damper layer like the small diameter Cutlass one. This drive shaft is heavily pitted so with it not having rubber in this one I am thinking about just getting the ends cut off and have a new tube welded in. Not sure yet what I will do for the drive shaft but wanted to post that this is a 4th version. .
