alternatives to an 8.75- what about an explorer 8.8?
Maybe I'l living in the past, but there were so many B-Bodies built (compared to A-Bodies), it has always looked to me like they were everywhere... but, I haven't been in a Mopar junkyard in a couple of years.
The spec sheet I have may be incorrect, but I've attached it, so you can look at the housing widths. I knew a guy who installed one in his '70 Duster and didn't even bother to move the spring pads over; just pulled the leaf springs half-inch sideways and bolted it down. I certainly don't recommend that, but it didn't give him any problems for the few years I knew about the car. He didn't even bother to get 4.5" back-spaced wheels... just used B-Body 4.5" bolt pattern, steel wheels. No fender interference, but, it was close, at the lip.
I can't vouch for the accuracy of this chart. If it's incorrect, somebody please tell me; I'll delete it from my files.
Hope this helps...
