So is that 4" wider than the Gbody rear?

As is it really limits your rear rim choice adding 1.75"+ to your current backspace.

I will probably have a friend of mine put c clip eliminater kit and narrow it at that time. Again im at $200 now with a posi unit in it.

Agreed but .75”-1” Per side extra would be nice. My Nitto drag radials rub the frame and there is plenty of wheel opening clearance with the factory rearend.
