This has probably been brought up a lot but does anyone know the width difference of the perches on a '67 A body 8 3/4 and a '64 B body 8 3/4? I know flange to flange they are pretty close but what other differences are there that I would need to know about? That Barracuda has the little 7 1/4.



64's have the spindle nut tapered axle deal.

You want a 65-67 B-body rear end. It's wider for sure. Check the Moparts tech archives and all the specs are listed right there:

1 5/8 wider on a 65-67 B-body rear than a 66-72 A-body 8 3/4. So you will need different offset rims (more backspacing) to compensate.
