I honestly don't know the answer to your question. I am helping a friend sell the rims. Perhaps other Pelicanites could share their knowledge with respect to this subject.
It looks like the part number is 951.362.115 on one of the spokes. And unless the 928s shared part numbers, the 951 prefix in the part number indicates a 944 Turbo.
I will do some more research on the rims today.
