Many glass shops that specialize in windshield replacements, will come to your place to do the swap. We have Binswanger in the Midwest and they do vintage auto glass replacement, as well as field swaps. I suggest calling a few in your local area and quiz them about their experience with your era of truck, as well as they fee to do the install.
I am having two windshields and two small back windows replaced on a couple of my '66 Chevy trucks and will have the glass shop come to my place to do the work and also request a quantity discount, since I have having four openings done. I will make sure I have the replacement glass and the proper replacement rubbers on hand.
