70-71 Window Slide Bolts

Looking for two 70-71 window slide bolts that go through the guides and into the plastic retainers.  Not sure if any place sells them, haven't hit a match yet.

Early E body uses a coarse thread with a screw thread clip.
B+C use a shoulder bolt thats the same size, but 1/4-20 thread.
So you need the backing nut to go with.
Thisevi got.

So I'm not sure what that flat disc is in your pic, but they came in my rebuild kit.  My setup users the bolt, a thick round plastic piece that connected to the glass, and a plastic slide that rides in the track itself. 

Do you have any assembly pics?  Also sending a pm
