[D.S.]

If there is a washer between the bolt head and bracket loose the washer for more clearance...
If that's not enough grind the head down a little...

If more room is still needed countersink a flat head bolt into the bracket...

It does have that one washer that you pound over to sort of lock the bolt.

Also, I forgot to mention that it does not drag when you spin the wheels with it jacked up. Only with weight on it. Of course I wouldn't have driven it if it did.

You could eliminate the washer with a little drop of #242 blue loc-tite then...

Must have been almost 0 clearance the bolt and rotor...
Were the bearings loose enough to allow the rotor to wobble?
