I have a 1966 Ford Mustang Coupe and I am replacing the driverside rear 1/4 panel and I was just wondering what is the full length measurements on the 1/4 panel. I need the very top, mid section and bottom measurements. I have an Repro skin and it looks 1/4+ bigger than I need.

 

Wish I could help you, Brian, but mine needs replaced too. Some bozo repaired it years ago with about a gallon of bondo, bit that still didn't stop the rust.
