CEN Racing Differential Parts List for Savage FYI

So this makes the deal on Sav Central where guy selling them either in bulks and shimmed or just the diffs with shims not look too bad. His last posted prices were $130 in bulks and for the parts, silver $115 and black $110. These are filled with 10k fluid.

I didn't know these were that expensive. What do they typically go for on Ebay?? I know about the red loctite and having to bake them to get them open, so paying him may be worth all the trouble/time its going to take anyway.
