how much do ya think???? $$$$

i'd normally tell you to go ahead and mod the crap out of a car, but an early 65 with a 260... you'd be taking away pretty much all the things that make a 64.5 special. why not find a plain 65 or 66 coupe, it will probably save you a bit on the purchase price as well.

but anyways,

power discs could be anywhere from 500-2500, from a junkyard granada setup to a baer track setup.

never done an ac comp or a gen-to-alt, so no help there.

you could probably get the power steering gear from someone for pretty cheap, as most people go the other way, from power to manual. then add maybe 200 bucks or so to get it in good shape.
