# 2 goes up inside of the dash area. I cannot remember which role it plays--would need to have my nose burried up there assesing the situation--but I think it's a bracket/support for the raido, heater, or dash itself. #1 & #3 must be 7 and/or 8 specific because I don't have a clue.
The part in the second photo goes on the top outside of the quarter, inside of the jam. The notched area goes around the glass.
