Possible driveshaft parts source...

I found this company on the pirate site. Rockford Drive Line. They make replacement parts (cv's, boots etc) for driveshafts (propshafts). They have parts for Isuzu Hombre(98-00), I350 (06), I370 (07-08)and Ascender (03-08).
Anyone know if any of these use the same flange type?

I wonder whether it would be a good idea to try to create a cross reference for patrs used by other vehicles.
