wheel adapter

I think it’s important to point out that an old 8-3/4 is only worth the cost of the housing and what a rebuildable 489 case goes for. They all need to be rebuilt and gone through completely. By the time you straighten & narrow it, buy new axles, replace everything and add disk brakes you most likely will be around $2000-$3000. I don’t know if that’s worth the cost... DTS here in Michigan rebuilt mine with my parts for $160. That’s too good of s deal to me.

I’m taking it the OP wants the get the car rolling while it’s being worked on. You could drive I like that, but it’s easier to just get your suspension work done then buy your wheels. Your wheels will always have a funky looking offset to them if you want to run adapters on that old 5-4” bolt pattern.

Can’t say I agree with that assessment of the 8 3/4’s at all. All of the ones I’ve run are original. No straightening, no rebuild on the 3rd members, only thing I’ve done is wheel bearings. The 741 case in my Duster right now with 3.55’s came straight out of the wrecking yard. Quick inspection and installed. My Challenger went close to 70k miles like that, my Duster is on its way to 15k like that.

Maybe on some big horsepower car you’d need to do all that, but I’ve only come across one housing and 3rd member I wouldn’t run as is. And I’ve pulled at least half a dozen complete 8 3/4’s out of the local yards. I don’t think I’ve got more than $350 into the 8 3/4 in my Duster at the moment, and that includes buying the B-body housing and stock axles.
