I'm in the process of a MAJOR overhaul of my 1976 Eldorado Convertible. One of the aspects of this job was to convert it from FWD to RWD using a Ford F150 rearend. I cut a transmission tunnel out of a 1992 Buick Roadmaster Estate wagon to provide clearance for the new TH400 tranny and the driveshaft. My dilemma is ordering a carpet that will fit the new tunnel and the rest of the original Eldorado floor pan, which was completely flat bacause of the FWD. I know that the 1975 Deville was a RWD, but I'm not sure if using that or a molded carpet for the Roadmaster would be a better choice.
