I believe the resin needs a C5 Corvette for the windshield glass.
For clear headlight covers, I would do a vacu-form of the nose. Even if you do not have a vacu-form unit, you can fake it. Make a frame to attach a 6+" square of clear plastic. Heat it up in an oven, just us it starts to gently sag, take it out of the oven wearing hot mitts, and quickly pull it down over the nose of the resin, pausing to let it cool.
Of course, you will still need to sculpt the chrome bucket reflectors. I just said "the heck with it", and sold my JF resin to someone!
