Hell, if you're giving him a Ford GT, tell him he can change those himself!
RS headlight system: I don't know what that is.
Seat inserts: Pop those in yourself by hand. Follow the instructions.
Horn emblem: Again, if you have one, do it yourself. It's stick-on
Windshield: This is not a minor replacement. To do it right, you have to remove the front fenders. Unless the windshield has a crack or major divot in it, I'd advise you to leave this alone. You may end up making more work than you planned. Otherwise, you'll want to take it to a shop that has done this before.
Ask for a good shop recommendation for a FGT windshield replacement in/near Scottsdale.
