I understand the stock rear-end for a '66 Mustang with a 289/302 should be an 8" and the in-line six's came with the smaller 7" or 7.5" If im looking for a direct 9" bolt-in to put in a '66, what would be some good donor cars? Trying to avoid any cutting or welding.
I'm not sure what's under my '66. It came with the 289, but I was read that all 8" came with five lug axles. Well, all my wheels look like they're five lugs, but it looks like one lug was cut off all four wheels. I would think if they were four lugs by the manf., the lugs would be spaced evenly. Just looking for a little insight before I start to tackle it this weekend.
