I'm detailing the rear wheel wheel wells on my 1969 RS Z/28 restoration project ("Brooklyn Z") and was unable to locate disassembly photos of this area. The wwells have received color overspray and now need to be undercoated. I'm conversant with the undercoating process however need to confirm
the location and type of plugs originally used in the three, 3/4" holes inside each rear wwell. Quarter panels are original to the car and I recall that my original plugs were a combination of Caplug BP 3/4" recessed style plugs similar to those used on the cowl (2 x 1/2") and on the firewall (single). The other type of plug used was a body plug style plug also found in other locations (floor pan, bottom of trunk drop offs). Below are photos of both types of plugs (web sourced photos). Below also are photos of Eddie M's Cortez X77 Sept 69 Norwood build (mine is a 2B Norwood build) which show only the body plug style plugs used in all 3 rear wwell hole locations.
What style (and mix) of plugs were originally used in rear wheel wells?
