Jeff I got a good idea for your custom headlights. I know you are not ready to do them yet but here is something you might want to consider.
Today I was sitting in the toll booth at work they decided to re train me because they changed the computer system since I last worked. But anyways since I was training all I was doing was standing there watching someone else do all the transactions and I was getting a good look at different cars as they went through the booths. I was looking closely at some newer jeep grand cherokees as they pulled up to pay. They have these nice circular headlamp reflectors in the headlight assemblies that look like they are separate pieces. Maybe if you stumble upon any of these in a junkyard you can check and see if they are worth a flip.
