The '66 Dana used a 7260 joint which is 2 7/8" across, the '67 used a 1330 joint which is 4" across. '68 and later used the 7290.

Looking for the housing flange to flange size on a 66-67 Dana l, I think it’s 5/8” less than the 68-70. Next question, how much inside tire room is there on a 66 Belvedere with stock rear? I can make the rear shorter if I have the room, 15 x8” rim and 10” tire, I don’t want to get to close to the outer fender I can ck over the weekend. My 66 Satellite has a dana in it

There is not alot of inside room with the leaf springs in the stock location. 4 3/4 is the optimal wheel backspacing for an 8 inch wheel. You can fit about 11 inches of section width without rubbing, maybe 11 1/4.
Any tighter will start rubbing the leaf spring in turns most likely. My slicks are about 11.6 and 28 inches tall and touch the springs on tight turns, only about 1/4 inch of clearance. If I space them out 1/8” they touch the inside of the outer wheelhouse instead. More clearance, maybe 3/8” to the wheelhouse that way (but I hate it scuffing the side wall).
This is with SS springs and regular shocks, I might be able to get away without rubbing with stiffer shocks or if the rear was higher (made in mexico SS springs sagged about 2 inches after a year or two), but if you have stock springs I’m sure it’d rub more.
