Hi FB
The bridge post hole on the low E side for a tuneomatic bridge is usually 1-2mm rearward than the high e side, this is necessary for proper intonation. If you have a guitar with this type bridge, or access to one, it's easy to see. Or just google tune-o-matic bridge, you'll see plenty of LP style that will show this.
Not the best pic, but both of these kit guitars have the same bridge and you can see the low E side post is set further back than the high e side
I have one of these kits, GPR-1M, I should get to. On the list of things to do. And mine does not have either bridge nor tailpiece holes drilled, it's how they were first offered.
