Being an owner of a real 1960 Corvette since 1983, I too have come across those AMT models and was very disappointed in the tiny headlights. The recent AMT kits were originally MPC and much better. I have the remains of an early AMT kit my kid brother built when he was 14 or 15. He is now 65.
I will be following this thread as I have 3 MPC 1960 kits to build, including the flip nose, my brother's AMT model and 4 of those multi piece Revell kits I purchased at Radio Shack in the early 1980s.
