I just swapped out the rigged powered window regulators for manual windows in my 86. It is very easy to do, just pull out the electric regulators and bolt in the hand crank regulators, but you will have to do something about the door panels. I was able to find the passenger side with no problems at the boneyard, but the driver side was very hard to find at the boneyard. I'm not sure how much a new regulator would be.
