NOS MoPar door glass window regulator
Genuine new old stock Chrysler part number 3824013 for the LH drivers side door. Non power window trucks. After 40 + years the originals are bad about worn out gears, and nothing makes the window roll up and down like it did when the truck was new like a new regulator with tight new gears !
Remember, there's no substitute for Real NOS MoPar!
