9-bolt PBR's on a 10-bolt
There's a REALLY nice thread by JamesC on this:

The difference is the bolt pattern:
Is there a reason we cant just clock the 9 bolt plate a little and drill new holes?

Yes, you should be able to. I think I swapped the LH/RH so the caliper would stay in the same place, if you swap them side to side, none of the bolt holes overlap so you don't have to re-clock the bracket

You can rotate them up or down a lil bit and redrill. Just make sure all the E-brake and fluid lines have room when you re-clock them, esp on the driver side because of the panhardbar mount on the rearend.
