Hank, In the Fussie yearz that sending unit "should" be the same for all three, Chrysler, Dodge, and Plymouth. I wouldn't bother looking for an NOS unit for your Long Roof. You'll still be looking when you've reached the point when your DMV refuses to re-new your license! Maybe Len Dawson, or GULP....Mitchell. Gawd I can't believe I even uttered that name. Personally I'd web search Moore's Auto Salvage in Rapid City, S.D., take the tour and check out their wagon supply in those yearz. Betcha they have what you need. Worst case scenario iz that it can be re-built but don't ask me who or where. The only guy I knew that did it went toez up 10 yearz ago! One other trick you can try iz to find a NEW replacement unit from an A-B- or C-Body of the same vintage for any of those 3 marques and GRAFT (Cut 'N Splice your rod and float) to the new unit and bend as needed? Necessity iz ah mother my friend. G.L. with it, Jer
