Have seen this mismatch on other examples. BTW did you find any labeling on the back side of the interior rear quarter trim?
Thanks as always for sharing your progress
Jeff,
I didn't find any labeling on this car, but I have seen other early cars with a file folder type label identifying parts. Chuck Cantwell recalls that they were initially concerned that parts from one car may not fit properly in another car. They soon discovered that this wasn't an issue, and the parts got mixed up but with no problems concerning fit.
