Driveline angles are very complicated. as I'm sure everyone knows. I just wish there was more information or a how to on this subject. I researched and asked questions before I finally bit they bullet and ordered the shaft. I know Nate will help me figure it out an I plan on doing a thread dedicated to this subject once I'm done.

You are correct, the transmission mount is to high. But that is were is supposed to be based on a max of 5 degree output shaft angle. The problem with lowering just the transmission mount without also lowering the motor, is the angle that it places the tranny output shaft. It currently is set a 5 degrees (probably the max you want). If I lower the the tranny mount to get the drive shafts at the proper angle, it create an 8-9 degree angle on the transmission output shaft. So the only way to fix that is to lower the motor mounts. Clear as mud?!

Honestly, I never really thought about the diameter of the drive shaft. I took it to the drive line shop and explained to him what I was doing and told him the motor/tranny combo that it was going to be connected to and this is what he built. I did a lot of research and asked a lot of questions but the diameter of the shaft was never mention as an issue. If the diameter were smaller, it would allow me to raise the carrier bearing up more, but as it sits, I already have it raised up 2.5-3 inches. I'm not sure I would want to any higher even if I could.
On a better note, the 68 S/C truck is coming together nicely so far....
