Door Rebuild - going in blind

[runpasthefence]

So, I let a friend of the family paint my truck, and when he painted the doors he took them apart completely and promptly lost a bunch of ****.

I've never had a set of these doors apart, so I'm putting stuff together slowly as I figure it out and as I order new stuff.

Anyway, on the left side of the picture below, there are a couple of holes where a pair of fasteners potentially held in a channel for the window to travel in...maybe. I'm not really sure. Does anyone happen to have a picture of whatever attaches there and maybe a source for the part?
