rfinegan,
Nice work and thanks for the writeup. Could you comment on locating the four bumper mounting bolt holes? Any tips would be appreciated. Do you intend to use nuts, bolts and washers for mounting? Or some sort of riv-nuts and bolts? Thanks.
Factory is bolts and lock washers. I decided to use studs by cutting the heads of the bolts and chamfering the ends and nylon lock nuts. This lets you install the bumper with one person and not have to align the bumper and try to get the bolts stated in the holes at the same time. 8mmX1.25x50 May be just a tad long but worked fine
Also have the Dog bones handy when you do this . They have the correct spacing/ the same as the bumper and can help ensure the holes are going in the right location
FWIW: I was Following the post here on Sticky on where to drill the holes, BE CAREFUL.. Mine were off and needed to be opened up/drilled again...in the right location. My bumper is not new and may have a few tweeks. Use you bumper to find your holes and double check before drilling
1) Tape the area where the hole will be drilled with blue painters tape
2) Cut the heads off the 8mm 1.25x50 bolts and screw the new studs into the top holes of the bumper.
3) I left the bottom valance on to help center the bumper. This will ensure the correct vertical spacing as the fit has just a little play/spacing
4) Center the bumper in the desired area and give it a tap with your open hand to mark the tape in the location for the top holes
5) Go back and measure the hole to the sticky in the forum (this is the relaity check)
6) Drill the holes with a 1/2 step drill. They are cheep and do a great EZ job on this
7) Insure bumper is desired location top to bottom and left to right. Open holes as needed to fine tune
8) Add lower studs and dog bones(optional but helps minimize scratches)
9) Install bumper studs/dog bones in top holes in new fine tuned location
10) Tap bumper for new location for lower holes on blue tap
11) Drill bottom holes with 1/2 step drill
12) Install and fine tune as needed

On a scale of 1-10 for difficulty
1=new gas cap/seal
10=Transition overhaul
This job is a 2-3. There is some drilling, cutting and grinding but can be done in a few hours (less paint)
I can measure my holes once I get the Gel cote tops. But for now they are installed
