If the truck never had ac then most likely yes. You could scrounge up used parts but in my opinion you would be making more trouble for yourself. Old parts make have leaky seals, be contaminated or just not function like they did when new. New compressors, condensors, etc. aren't cheap but in the end you'll have a good system that will last a long time.
