If you want to use the F-body rear axle you will need the perches moved to A-body width, the F-body perches are 44.5" center to center while the A-bodys are 43" c-c. Overall the F-body axle is just under 1.75" wider than an A-body 8 3/4 with BBP axles, meaning if you add about an inch to the wheel backspacing compared to an A-body

That's exactly what I did and It'll do just fine. I have M/T 26-9.5-15 under there and it just barely fits without fender rubbing. I do have room for a little shy of one more inch of back spacing with the same tire but I can't remember what I have right now.
