That assembly attaches with the eight bolts, four with some adjustment, to the car's frame. Yeah, that's hours of fun...NOT.
After cleaning the 55W foglight bulbs with alcohol (remove all grease + fingerprints) all bulb assemblies were inserted in the new housings, then functionality, initial alignment and clearances ensured. (I tried some LED turn signal bulbs; one side worked okay, but the other caused indicator problems in the dash.)
The front plate cover has two screws with J-nuts underneath and two Velcro-type attachments. This is the inside of the cover showing the 3M glue-on side:
The receptors are riveted, using reinforcement washers, to the new bumper cover.
I opted to make two braces where the bumper cover attaches to the air dam. The four braces, as explained below, are cut from 17 gage sheetmetal, each 3/4" wide and about 24" long. My template was traced from the outside curve, initially, then refined to fit the shallow groove in the poly-U. I intended to cut the curved pieces on my bandsaw, but Jerry, my artist/expert mechanic/body guy, recommended and used his shear to cut straight pieces, then showed me how to bend them with this cool tool:
The lever moves two jaws that grab the metal, make a small indentation and curve the metal the 'hard way'. It works like a champ. This is a few more hours as the pieces are bent, unbent, then bent some more to fit the template. Two identical pieces on each side sandwich the polyurethane Shinoda pieces. Slightly oversize holes were drilled in each bracing piece for the J-nut bolts to pass through.
Now it's time for more fiberglass in my hands and arms while adding more scratches and abrasions.

I was lucky to find this SnapOn boroscope at a decent price from a Jerry's partner; one of those guys who LOVES tools and has to have the latest and greatest. This boroscope, as you can imagine, has been wonderful to have available for jobs like this, where assorted lights and mirrors don't work real well. The tip has LED lights and the camera, which feeds the image through the 36" flex arm to the LED display.
The worst bolt is the most forward one, which requires alignment of two body panels, the bumper cover and the lower air dam, and the two stiffening brackets, one with J-nut like the others, but is waaaay up where ya cannot see.
Viewed from above:
These home-made brackets follow the idea of kit-provided ones for other panels and those used in all C4 Corvette assembly. I don't know why two short V-shaped ones were included for the very front of this assembly, and none for the sides. Mine were painted with Rustoleum gloss black, similar to the provided brackets, and will be all but invisible. This is the passenger side with much better access; the left side having the vacuum canister and plumbing in addition to the wiring and lights.
This shot shows the access holes under the air dam; the only way for a 10mm socket to reach the joining bolts. I drilled one more to access the front corner; the two existing and closest being misaligned for a socket assembly, but useful for viewing said misalignment.
Now that this is posted, I'll try to finish the install.
