These are exact replacements for 1964-68 Ford Mustang, but looks similar to the 1967-68 Mercury Cougar. This floor pan will also fit the 1969-73 Ford Mustang, but 1969-70 cars have different ribbing configurations. To use this pan in 1971-73 cars will require modification.
This heavy gauged stamped steel floor pan starts behind the seat platform
*NOTE* This floor pan has the outside lip bent down which is proper for coupes, convertibles were bent up. You can either bend it up or remove it and seam weld the pan to the rocker.
