4.5" bolt pattern 7.25" rear axles

Does anyone know all the models that have 4.5" bolt pattern 7.25" rear end axles that will fit the '69 a-body?

Is finding a '73-'76 a-body with front discs the only likelihood?...

Only A-bodies had axles that will fit an A-body housing without shortening. If you want big bolt pattern 7.25" axles, you'll need to get them out of a BBP A body with a 7.25

It would be nice if an Aspen or 5th Ave axle would fit. There's a few of those out there. Thanks.

The F body axles are longer. You can swap the entire housing over, they're only a little over an inch wider flange to flange, so you only need an extra 1/2" per side of clearance...

For that matter, grab an 8 1/4 out of an F body and use that.
