Everything I've read indicates G11 = tinted glass all, for 72-74 e-body. My 73 Challenger has 87,830 Miles with factory ac (H51) with original factory tinted glass all with Chrysler pentagram logo, and fender tag does not include code G11 . This indicates fender code H51 includes tinted windshield and tinted glass all. Implies code G11 is for e-bodies without ac that were ordered with factory tinted windows. Seems logical.
