CPP notch alignment question

[shifty]

So, I've had my frame cut for a while for the notch, and now that I'm getting serious about finally getting this in for sandblast and powdercoat, I'm noticing that the CPP notches just don't seem to align well with the factory holes on the spring plate. For the record, the frame has NEVER been unsupported, so I know the rails aren't bent from cutting the notch. I've had the notches clamped but not bolted.

Spring plate has three holes - one approx. 5/8" hole in the center of the spring area, and two smaller 3/8" holes on either side of that.

What I'm finding is that no matter how many clamps I throw on the notch plate to wrench it down onto the frame, those three holes are off by about 1/4". I can force the one closest to the front of the truck line up, but the larger hole at the center is out by a millimeter or two, and the one closest to the notch itself is out by 1/8" or so.

I already had to take a unibit to bore out the stock holes to 7/16". I'm just curious if you guys had the same experience, and if so, did you just waller out the hole in the c-notch plate with a drill or rotary tool or ??

i plan on finishing drilling out the plates tomorrow, then popping them off and hitting em with some paint.
