I typed it all up and the thread was gone now it is back
Rear 275/60/15 BFG Drags on 15x8 rallies from wheel vintiqes 4.5 back space leaves 5/8" from the springs and would hit quaters if someone rod in the back seat or going over bad bumps fast
Front is 215/60/15 on 15x7 rallies{same company} back space same as above
The rear might be a little diferant since it is a 8 3/4 with moser axels for big bolt pattern with 11x2.5 drums from a C Body and green bearings. they said they make them for the brakes used so the ofset is right.
