For anyone that is interested in performing this Eaton LSD conversion, I'm setting up a group purchase. I'm going to be purchasing the correct diff from Eaton for our application, so if you participate in this purchase you can save yourself the trouble of having to think.
The prices on these things seems to be skyrocketing lately. Earlier in this thread Ben said that he could get them for $325. Well, Jegs has them listed for $552, and are out of stock. Summit Racing doesn't even list them anymore. Ray Covino mentioned that Advance Auto has these listed for $556. Well, I've been in touch with Eaton, and they say inventory is fine, and I can provide a group purchase price of $415.00 plus shipping
as long as we get enough buyers. Honestly, seeing how much praise this diff has received since Ben started using it and I drove it at Nationals, I don't think we'll have any problems getting enough people together. If you want in, just e-mail me at firstname.lastname@example.org
If you're curious about shims and spacers, I want to get a diff in my possession and perform all the measurements myself. At that point I'll make the shims and spacers that I used for my car available to everyone. I'm sure I'll be able to snag a good price on those, not that they're all that expensive to begin with.
