The rear spring parts are the same for R and W car lines. Only the wagons have unique parts. As for the springs themselves, convertibles and wagons used different rear leaf springs from all the other models. The difference in wheelbase normally was due to length added to the floor pan just ahead of the rear seat. But in the case of the R and W models, the floor pan extension is the same for both. The 1965-68 C-body Fury, except wagons, was advertised as having a 119" wheelbase while the 1969-73 models was 120". For 1965-73 the Fury was shown as having a 119.5" wheelbase in engineering dimension drawings. These same drawings also showed Polara/Moinaco with a 121.5" wheelbase, Chrysler at 123.5" and the C-body 1967-73 Imperial at 126.5" All advertising material listed the wheelbases at 121" for 1965-66 Dodge, 122" for the 1967-73 Dodge, 124" for non-wagon Chryslers and 127" for 1967-73 Imperials. So, the difference in wheelbase may have been in the minds of the advertising/marketing people. Dodge was supposed to be bigger than the Plymouth, and the a/m people made it so. Extending the floor pan was a Chrysler trick dating back to at least 1934, as was extending the hood.. Bill Toronto, ON .
