915 output flanges vs. 944 cv joints

[trevorbrady]

Does anyone have a good knowledge of the output flanges of 901 and 915 transmissions and the CV joints of the Porsche 944?

I have 2 pairs of output planges (both coarse splines at gearbox end, I think 17 splines or so)

one pair have 6 holes on a PCD of 94mm, only 4 of which are drilled through and tapped. The o/d of the flange is approx 110mm



the other pair have 6 holes on a PCD of 77mm, and all 6 are drilled and tapped. The o/d of this flange is approx 88mm, and there is a "lip" folded down towards the cv side.



I am trying to mate these to 944T drive shafts, but the 944 CVs have a PCD of 6x86 and an o/d of 100mm. Since neither of these pairs of flanges suit the CVs, are there CVs out there that will suit either of the flanges or are there flanges out there that will suit the CVs?

This is a bit of a head scratcher for me, any help appreciated.
