New Window Channel Installation

[Lembomw]

I am in the final stages of rebuilding my 30 Tudor. Today I received the new window channel kits. Before I make a mess of this I thought I would ask how to install the new window channel felt. I looked through the books and past threads on the subject but do not find an answer. I have the kit that has the tabs riveted at the top and bottom of the felt channels and I see where the tabs go but do not understand how to get the top tab in without bending it. When the bottom tab is slid into the slot and brought to the highest point it can be move to, how to you get the top tab in. If you do not put the bottom tab in its slot I still do not see how to get the top tab into its slot since the tab is bent at a 90 degree angle. Even if I can get it into the top slot the bottom tab seems to be too high to start it into its slot. This must be an easy thing to do but I just do not see it. Would greatly appreciate instructions.

Thanks, Mark
