1966 Disc Brake Conversion Questions

As a new MOPAR owner/builder, my experiences in building these cars just aren't up to par yet. So that leaves me with a few questioms maybe you more experienced fellers can help me with. The main question I have at the moment is convertimg the front dru,s on my 66GT to discs. I know there are probably a handfull of aftermarket kits available, but I'm a bit on a budget and I prefer to build things using parts from other cars. I frequemt local salvage yards quite a bit, so I am wondering if there are vehicles I can be keepimg an eye out for to get parts I need to convert? What other vehicles will work, and what parts do I need to find? My buddy and I have discussed using and adapting the full discs from a 4 wheel disc pt cruiser, and we may try that route...I just want to see if you all know of something else out there I can find that might work better. Thanks guys!
