Suburban tailgate glass run channels

[James Lamb]

Hi all. I'm brand new to the forum, and a newbie to forums in general, so apologies in advance of I violate etiquette.

I have a 1989 Suburban 4 x 4 that I am putting back in road worthy condition. I have done major stuff, but here in rainy Alabama have just discovered that the run channels that guide the tailgate glass are shot. Driver side one is rusted into near non-existence.Passenger side one needs replacing but enough there tom copy. Unfortunately the brackets are different from the other - i.e. there two side are not mirror images.

I have been looking for replacement run channels for over a month. LMC Truck does not have them, nor any other internet supplier I can find. Soffseal was making them but does no longer. Have also called salvage yards as far away as Arizona, am finding that no one is keeping trucks that old. They're all sold off for scrap.

Anyone have any ideas where I can find new or at least good used run channels? I can't roll up rear window and we're having one of the rainiest seasons ever here in the Deep South. can't drive my truck until I fix it.
