I have a 84 240 wagon. I need the bumper trim parts; the ones that go across the top of the bumper. Does the sedan of the same period use the same trim parts on the back bumper or are they unique to the wagon? Do the later wagons (post 86)use the same parts as the previous wagons? We're running out of mid 80s cars down here in San Diego and I hope there's some commonality with the later ones. Also, I want a tach for my car. Does anyone know if one from a 740 will work? Thanks in advance!
