Terry,thank you for the clarification. Do you or does anyone in the Darrin Registry have a listing of the running changes that were made to the Kaiser Darrins as production was on going? I have a factory drawing of the top without measurements, and it shows what changes were made and when for the tops. Dates, car numbers and signoffs are on the document. I know body changes, and chassis changes were made as production continued, but I haven't seen any published information. Any info?
