915 question?

[flat]

Brent,

Basically all 100mm joints are the same bolt pattern. The early 944 (83-85), T4's, Thing and bay window bus CV's all are 100mm with the fine spline (33). They will fit onto a T1 shaft, but they are wider (thatn T1) so you will have to machine the shoulder on a T1 shaft to accomadate the extra width of the joint for the retaining clip. Alternatively, you could leave the clip off...? The 944/T4 joints have smaller balls than the bay window joints, so the 944/T4 ones can handle more misalignment.

I think for your setup the ideal solution is to get a complete early 944 axle with joints, and then change your stub axles on the wheel side to 944 early aswell, so you have 100mm joints everywhere.

The later 944 (86+) are also 100mm, but they are coarse spline and do not fit onto a T1 axle-shaft.

The big 930's are 108mm I believe...

Hope that clears things up,
Lanner

I got drastic and cut the entire rear torsion out to put a custom one in. I'm cutting about 9" from the middle so I can move the tranny up and forward. I don't have to worry about clearance as it's in a kit car. I took a rear torsion adjuster and split it in half and will weld each end on the inside of the torsion housing then fab up a mount for the tranny and engine support. Lots of fabbing but I still need to calc how far up and forward I can go without the 930 CVs binding. I think it's about 4" forward and up. ANyone else do this?
