part swap

Hello I'm new to this site,and of corse I have a question.I am familiar with 67 & up A bodies but nothing older. I am going to look at a 64 barracuda soon,it's a 2 owner car (suposed to be rust free).I have taken apart a trashed 74 dart some time ago for all the good stuff ,disk brakes ,sway bar,v8k member,8 1/4 rear...My question is how much of this will fit the 64.

The rear end, and the disc brakes {IF you kept the 1974 Upper control arms}

67-76 k-frame will not fit 1963-66
sway bar wil not fit.
