Welcome and howdy from Texas! Very nice looking Mustang. Your ideas sound interesting and you'll find members here are receptive to innovation. Keep us posted on your progress. Oh, and get used to CJPP orders being back ordered. They seem to have a track record of parts not in stock.
Lol! You had us there with the GB pics! It really looks outstanding. Don't forget to paint the black on the inside the hood near the wipers when you get around to the black. Many restored Mach 1's miss this detail.
EDIT: here's a discussion with pictures...
Personally not a fan of parts that are just dress up, but I wouldn't knock you adding them if that's what you like.
Still interested in how the brakes work out.
