4spd insight

tax season almost here and Im getting another parts vehicle for my dart. awhile back I found a 71 demon non 340 car but has a 340/4spd/3:91's. it was however a factory stick car so it has everything to convert my auto over to stick I think acouple of questions though

are 70-71 steering columns the same?

are the pedal assemblies the same, (besides having an xtra pedal for the clutch Rob:-D) ?

are the driveshafts the same between demons/swingers, not kinda sure with different wheelbases involved?

I'd also would like to install a pistol grip shifter which one would I need for a bench seat car?
