i want a strat pickguard that has these accomodations, and nothing else.
two hum spacing, 3 pot holes, and a les paul style 3 way toggle hole.

my questions are,
where can i get a pickguard like this?
(or tips on simply building my own)
what is the standard les paul toggle hole size?
Just buy one of those pieces that you can cut your own pickguard, really handy.
I think warmoth will actually make a pickgaurd to any combo you want, same with WD. Check them out.
