I must be dense. On my 70 AAR cuda I cannot figure out how to remove the "L" shaped plastic trim that goes under radio and up and around the ash tray. I pulled ash tray cover/insert. Then on the trim piece I removed the trim screw on the side and the two hex screws on bottom.. Radio now slides out but plastic trim piece is still rigidly in place. I don't want to randomly start disassembling more of the dash. --The similar trim piece to the left of the steering wheel came right out upon removing its screws, so I'm a bit confused on this one.
