Hello all, I have a question; I am contemplating using an A body 8-3/4" housing in my 67 Belvedere II, and will have to upgrade to the big bolt pattern axles. I vaguely recall from the last time I bought big bolt pattern axles that they stick out a little further from the axle housing to the wheel flange than the original small bolt axles. Am I remembering correctly, or do I need a nap?.. I am trying to see if this is feasible swap with existing wheels, or will I have to narrow a housing. Thanks to all.
