I'm sorry that I didn't see your post earlier. I did the Sac Ford 1 piece window kit on my 57 F100. I love the look of it and now that it has broken in a little the windows work great. I wouldn't say they are EASY to put in though. You have to use a hack saw down into the window opening to cut out a channel for the window to sit. It is super tight and hard to do. If your truck is painted like mine was I would suggest LOTS of masking tape to protect the paint. The only other thing is the brackets they give you to hold the bottom of the channel were kinda cheesy so I made my own that bolted to the tab that the original window stop bolted. If you have some mechanical ability they are not hard to install though. No welding unless you make your own brackets. I think it was worth the money. Those trucks have very small factory windows and I LOVE having the 1 piece. Hope this helps.
