Hope that makes sense - I will see about getting a picture this evening.

Thanks. That's what I wondered. I did mine back in the early 90's before stuff like this was available. I used hardware bolted to the factory brackets w/a plate sandwiched between them on the inside of the bumper. Installed the bumper, tacked/welded the plates to the back of the bumper & the hardware to the plates. Then cut the heads off the hardware & welded the holes up from the front.
In retrospect, I should have just welded regular hardware to the plates on the inside vs the bumper face & the plate. The plates helped spread any impact load (which worked). But, since the bolt was still welded in the OE holes as well, they puckered when it was involved in a fender-bender. You know what they say about hind-sight....
