disc brake conversion cost??

[jlaird]

I just spent awhile reading through past posts on doing the 73+ drum to disc brake swap with the use of a donor truck. My question is, what should this cost from a salvage yard. I want everything to do the swap except the spindles. I also don't want to swap the crossmember. I was also thinking, what are the chances that the rotors will be good? How can you tell? (sorry, newbie here.) I have a 69 c10.

thanks,
