Caliper bracket bolts
supposedly I've read that the brake caliper bracket bolts are supposed to be replaced when working on the brakes. Well I've always reused my bolts. But I had to change one of my rear wheel bearings. After I got it all together one of my caliper bolts decided to dig into the rotor. Thankfully the pad won't make contact on that spot but still. Could my bolts be stretched out or could the wheel bearing that I installed maybe not made right. Also I tried to find the brake bracket bolts online. Couldn't find any. Not even from the corvette vendors. Anybody have a source?

caliper bolts
Have you tried your local auto parts stores? I don't believe they could have stretched that much. It seems more likely that the bearing might not be seated correctly and that's is what is causing the interference or you got the wrong bearing.

Well ok it's an 89. Before I put on the other bearing it had no issues. The bearing I got is an orielly brand bearing I had laying around. It's the abutment bracket bolt that rubbing on the rotor.

Is there a part number on the bearing assembly? Could be that the hub you installed is for an 84-87 C4.
If you can, remove the new hub and sit both of them down on a flat surface Are they the same height? Could be that the O'Reily's hub is for an 84-87 C4.
If the two bolts cleared the rotor with the old hub, it's entirely possible that the new hub is not the right part. You could also take that new hub back to a local O'Reillys and have them bring out another hub (make sure they get the correct vehicle description) then compare the two.
For your car, the O'Reilly webpage shows two rear hubs. Looks like the big difference is the number of years for a warranty.

If you remove the caliper and the rotor you should be able to measure through one of the holes on the hub flange to the plate/bracket that the abutment bracket bolts to. I have an old one here and I'm something very close to 49mm (hub flange to the abutment bracket support). You should be able to do the same as a comparison to the one you removed.
How about this, if you turned the aluminum plate/bracket backwards you would change the relationship/dimension also. If the aluminum plate/bracket is installed correctly I believe you should be able to read the casting number. I don't know that you can even install it backwards. I don't have a loose one to look at. I'd think not!
The service hubs for the rear have been the same for over 20 years so I'd think that's less likely.
How many threads through the aluminum plate/bracket?
