I now have 930 size output shafts (redrilled to 944/VW Type4/VW bus size CV bolt pattern), 944 CV joints, early turbo aluminium trailing arms, 944 turbo drive shafts and it all works nicely.
these are the 930 output shafts: the 930 CVs use 4 bolts and two dowels, the arrows point tot he 944 CV PCD holes drilled and tapped
