Quick update - rear bumper is in! Will post detailed pics. We were lucky to have a 318is right next to the DB vert so we could do detailed comparisons.
Bottom line:
-- NO rear bumper mods required, EXCEPT for a small hole for an M6 bolt that sits UNDER the bumper trim so it's not visible
-- NO cutting / drilling of the body required
You DO need to attach the sides of the rear bumper to the car differently:
- don't use the coupe side bracket mounting hardware.
- pop off the ends of your bumper side trim from the rear bumper
- drill a hole in the bracket that's attached to the rear bumper in the spot that lines up with the existing hole already on the car. It's about centered between the 2 slides of the bumper bracket, and about 17.3mm from the edge of the rear bumper trim, measured in line with the hole in the body. (pics will show you where this is)
- notch a metal fender washer and use it between the outside of the rear plastic bumper cover and an M6x30 bolt (not sure on the length - will check)
- run the bolt through the fender washer and the rear bumper bracket. through another fender washer on the other side of the bracket and locktite the assembly together with a nut.
- repeat on the other side. You now have a "stud" you can feed through the existing body.
- the sides of the rear bumper will rest on the existing slides of the bracket against the car.
- throw a rubber washer and a flange nut (or washer+nut) on the inside of the car (you DON'T want metal on metal contact).
DONE.
