I'm sure this question has been asked before but what Mopars can I rob parts from to do a disk brake conversion on my Dart. I'd like to do an aftermarket kit but the funds just aren't available right now. Any help would be greatly appreciated.  

if you want a disk brake setup so that the parts are readly available steal them from a 74 and up A-body. Make sure you get the spendles, caliper brackets, and upper control arms. Everything WILL bolt in without any altercations. I had just put this setup on my 64' Valiant and it works great, no problems and about a days worth of work.
