Cab to frame bushing worries.

[In The Ten Ring]

My front cab-toframe bushing bolts were tac welded in at the factory (thanks for nothing GM!). Anyway....I have those out now but my floor holes aren't perfect....

I've ground down the old tac welds but the driver's side hole is anything but flat.... (pic is of the passenger side which is much, much better than the driver's side).

Is this something I need to worry about? Will my new bolts align properly with the holes in the frame bracket?
