trying to picture T800 wing window.... Does it have a rivet through the little swivel thing ? (sorry for my high-tech terminology) if so, I think you just have to drill out the rivet and then replace it (either with a new steel rivet or a bolt with two nuts) when you put it back together.
Hmm maybe. It has a post on the top and bottom the goes into to the frame around it. Maybe the posts are spring loaded an you pry one down? Thanks for the tip, I'll go look at it again
