Question 944 Driveshaft / CV confusion

Hi, I have type 181 output flanges fitted and have late 944 wide Alu trailing arms, but I'm very confused about which driveshafts I need.

The CV's are 100mm diameter at both ends (normal 944) and the distance between the output shaft and the outer flange is around 21".

From what I've read on the forum I think 1987-1988 944 turbo axles should be correct, but I'd like to be sure before I shell out $$$$$$.

I going to buy complete new axle assemblies (CV's, axles & boots) so I'm not too worried about being able to interchange VW parts.

Thanks

I've had it confirmed by a porsche guy, that the only difference between the 86 turbo and 87 on turbo driveshafts is the number of splines.

The earlier ones being 33 splines and later ones 25 splines, so as long as you are buying them complete with CV's it doesn't really matter.

The lenghts are exactly the same for both versions.

I've now got a set of 86 turbo driveshafts on order, so I should be sorted, but I hope this info is helpful for anyone else doing this conversion.

You can use '87 and later 944S (DOHC-16 valve) axles too. The 944S, and S2 had alloy control arms, and these axles, and the turbo's axles changed to a coarser spline pattern.

They're 33 splines, and 21.5" long.
