Glass run channel

[brown7373]

I need a similar part I think for my 89 Suburban. I need the 2 vertical window channels that go in the tailgate to guide the window when it is lowered into the tailgate. I tried everywhere online, but went to my local Chevy dealer jus now and ordered them both. An 89 is much newer than yours, but did you try the dealer? Not sure what later model Jimmys take the same part.
