Ditto...
I ordered mine from Tower....
If I were to drill them, I'd be using a drill press with a perfectly level table to keep the drill straight. Would even check with a square to be sure..
Hand drilling is a no-no... Use a reamer instead...

I use the Fox reamer and it is very nice and good quality. Just make sure you start one side then go around to the other side and that keeps the hole straight. Works great.
