Help with Identification

Can someone please tell me what this is... Arrow, Ram 50, D50, Mighty Max?? What years of each models have compatible parts. I need tail lights and Tailgate...Thanks

It is all of the names you listed. It was imported by both Plymouth(Arrow) and Dodge(D50/Ram50) and made by Mitsu(Mighty Max). Parts from 86 down(all same body style, 87+ is newer/different) from any of the listed models should all work.
