The only major exterior pieces left to install in the long resto of my '65 fastback is the front bumper and front valance, but I can't determine in what order to do it. A couple You-Tube videos show the bumper being installed first, but in conversations with Mustang owners, the advice is all over the map suggesting valance first, bumper first, etc. I sure don't want to install & adjust the bumper first and then have to pull it off and change the sequence. Any and all suggestions of where to begin would be appreciated! Thanks, Ron...
