: trans crossmember

07-18-07, 04:10 PM
Hello All:upon inspection of the bottom side of the Big Old Girl [1979 sdv]I noticed,or it seemed that the pass. side floor pan is not as deep as the drivers side pan leaving more room for the exhaust system,with that said my question is does the double hump trans.cross member from a 9c1 or a fleetwood with duel exhaust work without mod? I have not seen the underside or config. of any one of these cars,imput,pros,cons please.

From what I've heard from others, it works without any floor pan mods. I have dual exhaust on my '79 SDV, but the muffler shop took the easy way out, and just ran the 2nd pipe under the crossmember and flattened it a bit so it doesn't hang down too low. I plan on doing it a better way someday, but for now it works!
