Just saved myself $5000, Ryne of Cunningham Motorsports found the cause of the rear end issues, although having 800 HP at the crank means beefing up some parts, so instead of going the original route, we're going with the Eaton Detroit Truetrac 32 Spline Differential. Ordered from Summit Racing, the part is in route from Reno, NV and will be at CMS by Monday morning & pounding the streets by Tuesday. Whew, great job CMS!!
