V8R Engine mount + BossFrog Diff mount??
 

I am thinking about getting the boss frog rear diff mount and a V8R engine and trans mount. I like the respective companies products. Has anyone done this? Also, any of you use a 03+ Cobra 8.8 rear end, 32 spline?

I was the guy that developed the Cobra rear for Boss Frog. Modified one of their mounts when my Cobra 8.8 wouldnt fit the plate. Not their fault at all, I didnt use the rear chuck they spec'd for the build. (see my intro for pictures) Though I have to say I am happy with the performance of the rear and the mount itself, the Cobra's size eleminates running the exhaust through the rear on the driver's side. I ran flattened 3" pipes under the center of the diff but next time would run 2 1/2'" duals to a 3" single on the passenger side as there is more clearance there, then into a muffler with dual outlets. I dont think the flow would suffer.
BTW, Cobra 8.8 Aluminum IRS has 28 spline axles....at least the one from the 04 I got mine from does.
