Saw you posted on FB too. Tried to answer your stuff there as well. Many of the parts you seek are not 4 door specific, so you should be good there. There are quite a few grille sets on EBay right now. Bumper shocks are all the same for all 74-77 A bodies. Not sure about 73, with the smaller front bumper. Not sure if there is a difference with the 2 door vs 4 door sport mirrors. Back portion of the rear seats normally gets beat up pretty bad by sun. Mine have dry rotted and I have them
