So mock it up and cut the section off vs grinding the metal bit by bit.
I have a Makita die-grinder...about 1 foot long and straight...this is the high speed grinder I was saying.
I'm also thinking of different approach...
First drill with small bit. Then gradually use bigger drill bits till grinder bit can fit into the hole. Then spread from there to grind them out to desired width and height.
