Well, I'll be a monkey's uncle... Yer right, Rusty- Doctor Diff does offer conversion axles for the early 7.25. Must be a relatively new offering, I had never seen those on his site before! They might even make the early 7.25 somewhat durable to boot.
OP, here you go:
Mopar Axle Pkg 7 1/4" A-Body 5X4 1/2" Bolt Pattern (pair) (doctordiff.com)
And that's dirt cheap for a pair of axles, kiddo. I assume you still need to score some B/C/E brakes for them, though.
Edit: He also offers 5x4.5 BC 9" or 10" drums as part of the package- it may mean you don't need B/C/E body brakes (like you do with most 8.75 axle packages), and these axles use the standard A body flange offset? He's on vacation until Aug. 4, so you'll have to wait until then to call and ask!
