Crash, I am with you. Unless I was building an out and out 100 pointer I would simply apply some WD40 and white grease and put it back together.
Those parts had a very thin zinc plating, there was rust on them thirty years ago, the windows have been working just fine all that time. Lube them up and get back out on the road with a smile on your face and the tunes cranked up.
