Weld up the original holes with plugs and re - drill the new backing plate holes. I did this on an a before and the oblonged hole method shouldn't be done. The piston ring that acts as a spacer that comes with the kit cracked on both sides while tightening the backing plate bolts.I took my backing plates and spindles to a laser cuter I know and had the spacer ring cut out of steel instead of using the piston ring. I welded it to the backing plate.
