my 440/727/ A-body 8 3/4- 3.91sg

FYI,,, A-body 8 3/4 shares same 43" perch centers and bolts in on top of springs with a shackle flip to tuck 12" rims with a 29x15x15 M/T in the fenders bed tubbed to frame.

with a stock truck axle a 10 rim with 7.5 backset will tuck the 29 M/T in there with it tubbed as well

my 73 c-body 8 3/4 same as 72 truck 8 3/4 at 59" flange to flange

my 67-c-body 8 3/4 is 56" flange to flange. nice for 10" rims
