Re: Rear end interchanges?

10-bolt after 81.
60-66's could be 12-bolt 30-spline or 17-spline.
60-64's also came w/the old 'drop-out' style differential that was different vs. the 'traditional' 12-bolt housings.

Panhard bar mounts are different on the earlier housings. Aftermarket 'long' PHB's relocate the bracket so that's not that big of a deal on the keeper, but something to consider on the one you'll try to re-sell.....

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
