AHAAA, It COULD have been equipped with an 8 3/4" axle IF it had the towing package. NO 8 1/4" A body axles until 1973. ALL A body 8 1/4 axles were big bolt pattern. ALL A body cars used the small bolt pattern through 1972 EXCEPT the '68 Dart/Barracuda SS Hemi.





As far as I know 73-76 still used small bolt pattern if it was a 4 wheel drum brake car. That would be 7 1/4 rear axle only, 8 1/4 would be a disc brake front and big bolt pattern all around.
