Am I Crazy For This Idea?

The rear end is not a bolt in deal, I think it has the ISO spring perches, and I think it is also a little wider, but that can all be changed.I think the drum to drum width difference is quite a bit, which with skinny donuts I think it can still work.
The A body perches are at 43" compared to about 44.5 on the Fs.
I think the Fs are about 3 inches wider,drum to drum.
The F body has a B-body brakes on it;which are the same as the 73 up A-body V8 stuff, so as long as you take everything between the control arms and including the upper control arm (leave the shock), I think you can make it work. I think.
Your 73 slanty K will not accept the V8 without custom Schumacher mounts.
Your rear crossmember will work.
The driveshaft may have to be custom.
I think I got it right.
