The plan is to cut from the back floor to the upper firewall and graft that onto the cab of the Plymouth. I am going to graft the instrument panel into the Plymouth dash and reuse the steering etc. I am also going to try to reuse the seats, but I'm not sure I have enough width in the Plymouth cab yet - it's going to be close. I'm trying to leave the steering, brakes and engine harness all stock so I know it all works - no use re engineering it all. I'm pretty sure I have enough room under the hood for it all to fit. I am going to have a custom radiator built that is tall and narrow like the original Plymouth because the radiator support is pretty integral to the placement of the fenders, inner fenders and hood, and the nose is a lot narrower than the Dakota nose.
I guess I can call her PlyDak when I get done. At least it is not on a S-10 or Ranger chassis.
