i've got some rust issues on my 72 es, and i'm having problem finding information, on rust repair panels, seems like thing i find, is some archaic website, that looks like it has not been updated in 10 years, or it's in another language, all together. i know the quarters are the same on the E and ES. but i need to find the metal below the bumper, and around the tail lights, and under the rear hatch. does anyone manufacture the ES specific patch panels, or am i going to have to fabricate the stuff myself?
