I think at the least you want the rear diff and the drive line close to parallel when you hit it. As long as it does not rotate past parallel.
That would be my 7 deg, adjust it by 4 deg = 3 deg. I am just looking for confirmation and maybe a referance information about how far to space the trans down.
I guess that I could just crawl under it with a bottle/screw jack, loosen the trans bolts, drop it down that 4 deg and measure it.

Thanks John,
