Porsche 930 CVs will not fit a VW trans or stubaxles without adaptation.
Weddle makes 930-pattern stubs, and trans flange-adaptors are available. I
do not know what the 930 bolt-size or pitch-circle is, but I am looking for
a set of these CVs to fit my 84 for its eventual Porsche G50 trans
conversion.
