hey Pete, I used the factory plate bracket, what we did was dremel the plastic off and then used a marker to mark the plate and then removed it and cut it. Leaving the plate on kept the plastic from moving while we cut it so we got a nice clean cut of the plastic and it required very little sanding to take away rough edges. It's a slow and tedious project but we still knocked it out in less than 2 hours. Thanks for the feedback. I'm not the 1st to do this by no means, just copying what others had done.
