You can spend hours cutting out rust and patching holes, but why bother? These reproduction floor pans extend the full width with vertical flanges for easy installation, and fairly well represent the original stamping. They have added metal to include the side of the tunnel on rod change cars. Just trim this extra material off for pre 1973 round tunnel floors. A true full MKi/2 floor pressing is available for the purists as FS006R.
After the 1990s the floor shape changed and we would recommend fitting the front to rear R/H panel HMP441004.
