74 dart swinger interchanging?

As far as I can recall the brakes would be a bolt on (upper and lower control arms too), though I would pull the k member and use the entire thing to also get rid of the funky '67 idler. (keep the old stuff for potential original value but use the newer tech) You also would get a v8 spoil mount and the big bolt with decent brakes. The rear end would be a drop in and most likely a 8 1/4 with bbp. Not to mention all the other stuff you could sell off the car.
