Mounting ideas:
1. Make two simple right angle brackets and bolt to the front of the tub.
2. Take 2 pieces of alum plate 4 x 2 x 1/4 and loctite a stud into each. Bond to the underside of the bumper so the studs line up with the holes in #1.
3. This is the clever bit
hang the bumper on the brackets by the studs. It will flop around a bit but it will hold the bumper in place while you work on the other monting points - making it a one man job.
4. Bond 2 more stud plates to line up with the stock bumper brakets adjacent to the head lights.
5. Mark through the holes in the sheet metal and drill the upper surface of the bumper.
Note that the centerline of the cooler aperture is not aligned with the center line of the car. It's off a bit. At least mine was and based on pics the RSRs were as well.
Second clever bit. If you find that the top edge of the bumper does not fit snug against the hood all the way across, you can slot the holes in #1 to give a small amount of adjustment.
Measure once, cut twice
