Door Glass Woes, any help would be appreciated.

[Gumby83]

Hey fellas, so i am curious if any of you fellas have a solution for me. the channel that the door glass sits in that rides the regulator up is all rusted to hell on my truck and no longer fits between the window scrapers i replaced (old ones were destroyed). so now my windows dont close all the way, they get hung up. i would like to know if there is a part i can order to replace the trays in both doors, i can find regulators but they dont seem to have the bar the glass sits in. does the glass come with it or something?
