You may want to get the cross pins as well. MX040 iirc...
they have a few different case covers too for whatever reason. Tower may have another that would work.
I just did all this(made a bunch of converted diffs for flux) and the gs202 is NOT the right gear. You need this one: http://www.cenracingdirect.com/index...arch=GO&Page=1
The 202 has a WAY TOO BIG hole for the output cup to fit into. Unless I'm a complete retard, the thing just won't work and I have both parts here to prove to myself I'm not a retard... but that's another discussion...
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.
