The SG clutches and R&P I have had for a few years. The bearings and seals were from rockauto. The spider gears and axle end gears came from Silke's Auto Parts Inc in Jacksonville Fl. But I think I got the last ones. You would need to call and check. Spider cross shafts didn't locate after about a year of looking. Basically just need to Google the part by description, and/or part number and hope something pops up. I do that about once a week, if I'm looking for a hard to find part.
