No, no, no, my son...
E-body 8 3/4" axle housings are a dime a dozen... Standard on the B & E bodies...
The standard axle on the a-bodies was the 7 1/4" axle that breaks very easily with a mild V-8...
A body 8 3/4" axles were only available as standard on the high performance A-bodies original with the Formula S or GTS 340 and 383, and optional on the lower V-8 models making them rare and expensive...
There is no way anybody in their right mind would trade an A-body 8 3/4" axle even for an E-body axle, much less throw in extra parts....
You must be new here... Good luck with that...
