55.2-59 Door Window U-Channel Installation

[GEF56]

I'm replacing the U-Channel seals on the door windows and I can't remember exactly how it goes together. The replacement kit has no instructions.

It doesn't seem like the U-Channel seal should fit into the U Frame on the vent window support side, however it will need to be forced in, and before I do that and bend the seal, I need some guidance.

Also the replacement kit comes with two strips of adhesive backed felt with instructions to cut to 34 inches, but I have no clue where this would go.
