well for those of you that like pictures here it goes.
if the pictures are in order.........
#1 i found the four corners with a 1 inch hole saw so they would have a radius, then cut it out with a cut off wheel

#2 all of the way cut out and sanded with a flapper wheel that fits into the die-grinder

#3 i put some of the door edge protector around the edge to make it look good

#4 front picture with hitch installed

#5 side view with hitch installed
