Wilwood kit vs Dr Diff Wilwood kit, help??

Call Cass at Quality Body Shop Drivetrain and SPEAK with him. He spent time with me getting my issues sorted. I couldn't be happier with my S-60 and disk brakes and proportioning block, et cetera. He won't sell you **** you don't need. The S-60 was about $300 more (cheap insurance) than an 8 3/4, and was available immediately, the 8 3/4 was on backorder, not a hard choice. The downside is I can't swap the pumpkin out in a couple hours.
