I'm going to cast another headlight, then if it comes out OK, I'll glue it to the original master and make a final mold. This way I will be able to cast a pair of headlights at a time. I've got the grille, grille bar, and headlights in silicone waiting to cure.
Here's the setup for the headlights.
After I shortened the back bumper I noticed it wasn't straight. I cast another one and got it right this time.
