I remember Larry Westwood from his shop in Milton, Southern Performance in the early eighties. Built the motor for my 69 Mustang which still runs strong today. Was (is) the best and most knowledgeable mechanic I have ever met to this day. You can see from his son's work that the apple didn't fall far from the tree.
Am I getting the basic idea right - Bond has an RX-3 modified into a race car, notices that RX-3s have become expensive to repair so decides to have a one-off car built as a replacement. It is better to have a custom shop replace banged-up unique panels from scratch than to source existing replacement parts? Perhaps they keep good notes to reproduce panels quickly? At least there is no guessing where to drop the car off for repair.
