Where to buy plastic door sliders on 1968 charger?

[javakmcharger68]

Need to replace the plastic slider on the drivers door that clips on with (two white plastic peices) the height of the glass in a metal bar. Need plastic push in tabs to hold the glass on the metal slider on the bottom of both door glass, & replace the padded metal strip that runs along the window glass(clip in type). Where is the spot to shop? Thanks for all your help.

They are called "vent window channel weatherstrips" and are pretty expensive for a piece of felt covered plastic..
You can get them at RPM Resto Parts......scroll down to the "Glass Channel" section

$50 each....$100 for the pair....what a bargain!
