As part of converting my Road Runner to manual brakes I got a new firewall stiffening plate and it has two holes at the top of it for two wiring harness brackets like this:
. These are listed as being '71-72 brackets and my car is a '73. Can someone please confirm that these were only used up to 1972 and not later? If so then should I weld the holes shut on my new bracket, repaint it, and then used the single, stock style bracket that was on the car before with power brakes to make it look correct for a '73 car, if you could even get a Road Runner with manual brakes in 1973?
