Got a set of upper door frames from a forum member back when I was doing the half door project. They need the flat plate piece at the bottom, though. If you're interested in experimenting with them, they're yours for the shipping cost.Huh. The replacement top arrived today, and they sent me a whole new top including new uppers for the half doors. Kudos to them! Anybody got a set of stock upper half door frames they want to part with? Time to experiment with installing sliders!
