Thanks for the feedback. The 66 has the bolt on subframe. My "Imagined" options were:
1-cut stock subframe and graft in the Dakota parts like a camaro subframe graft.
2- Replace the entire subframe by cutting the dakota frame and welding brackets to it that would bolt to the car (of course other adjustments would also be needed)
3- Use the whole dakota frame under the car. wheelbase/trackwidth wise this fits, but I would expect a LOT of floor work to make it work. I would go this route if the car had rust issues, but it doesnt so I dont really want to chop the floor all up.
Yeah I know the suspensions arent radically different, but its a whole lot easier/ cheaper to get Dakota parts ;-)
My biggest thing was wanting Power steering and since I HAVE the dakota frame now, I thought I should look into the swap before getting rid of it. I think at this point maybe I should just focus on the Engine/trans swap and i'll let the dakota shell/frame go to someone who can use it sometime soon.
