I've got deposit money ready for this. I'll take one for the community. Mark me as interested with money in hand.
I want this to go into production. Think of all the future owners with broken axels. Guys, I want them to have options. M-Factory is a fantastic manufacturer have for transmission goodies (IMO).
I'm getting one of their differentials as *soon* as my stock clutch goes. Now it's at 72k miles, bigger turbo, still holding so far (not sure if I should be happy or disappointed that to the fiance I can't justify opening the tranny yet). I've seen their products before. Really good stuff. My #1 choice to replace the stock open differential right now.
