I don't know the year, I don't have any pictures, but the number on the nosecone says 901.301.301.1.R if that helps.
I'm not sure about the 944 Cv's and 930 flanges. But (i'm not an expert) Wouldn't both Cv's be able fit on the same axle? I know Porsche and Vw have differant splines on the axles. But maybe the two Porsche Cv's have the same splines, basicly you can use 930 Cv's on the Transmission side and 944 Cv's on the out side.
That's a lot of guessing on my part, cause I don't know.
Can anyone else help with this?? please?
