I pulled all the 4-speed stuff out of my 440, 4-speed, 71 Duster w/ Semi-chassis headers. On the drivers side 2 pipes dumped into the fendwell and on the passenger side only one pipe dumped into the fenderwell. My best friend welded for me back then; he modified the bellcrank and made a new bracket for the pivot on the scattershield. I still have those parts and will reuse them or make new ones to fit. I know it won't be easy, but I'm going to try.
