Nope. It’s an 8-3/4is that housing an 8 1/4? if so, it probably came out of a volare/aspen.
Thanks. There wasn’t anything in there as far as a spacer/isolator. I wonder why an isolator, they’re bolted so tight I don’t think it would make a difference.1/2 is pretty close. Seems to be a variant on center bolts. Someone hogged those out for later model isolator's.
