I would like to see you fill in the bucket space around the bulbs with the same technique used to build subwoofer boxes - so that they have a natural flow. It is my understanding that is done by attaching and layering the fiberglass cloth around the woofer so that it looks like it is being push through/against a sheet of fabric.
Also, I'd like to see you figure out how to attach the lense without using a screw through it - or if you do, epoxy it as a stud from the bottom, and trim out the last 1/2" to 1/4" of the lense in black paint and seal it all down to the body. In other words, create the most OEM look possible so those that don't know anybetter assume it is some new form of Vette...and those of us that do know better will bow down in respect at the extra time and effort made to take it beyond the level of a custom car---into something else all together.
Keep up the good work. Hammerhead is going to be down right nasty!
