Same technique as above. I used threaded rod, extended it thru the frame holes till it touched the fiberglass. ( I secured it with a nut on each side of the frame) Marked where the hole should go by tracing around the rod on to the fiberglass. I drilled a very small hole from the inside of body to outside, just to locate the holes and make sure I liked where the placement of the bumper would be.
