The instructions for the PTB say to use a couple c-clamps to hold the tooth bar flush up against the bucket while marking and drilling the holes on the side of the bucket. If you clamp it per the instructions, do the clamps draw it up flush with the bottom edge of the bucket? If so, then do that and mark the holes and drill them.
If so, then there could be a bit of a weld where the cleat is welded to the tooth bar that is keeping the bar from sitting flush. Pull it off the bucket and check that. If that's the problem, a quick swipe with an angle grinder should fix it up.
Yeah I beat it pretty good with a 2lb dead blow. the issue is the cleats go higher and forward toward the middle of the bar. thanks for the input.
