915 output flanges vs. 944 cv joints

[Michael Ghia]

Alex,
If you want to use 944 arms, no matter which arms they are (steel, narrow ally or wide ally) then use the driveshafts complete with CV joints which come with them.
In order to marry those driveshafts up to the 901 tranny, you will need output flanges from a 911SC 915 tranny.

The early 901 comes with small (T1 size) output flanges and the late 901 comes with 930 size output flanges. The 914 box comes with T1 size output flanges.

Another way to make stuff work would be to use the early or 914 output flanges (T1 size) and swap the CV joints over on the end of the driveshafts with T1 CV joints... that said I have never tried this so you'll be the guineapig! I suspect that the splines on the shaft will be the same but that you'll have to use an extra spacer on the splines before you put the cv joint on as the T1 CV joints are narrower than the Porsche ones.

Good luck, if I lost you please say so and I'll try to explain again.
