Hi everybody kinda new here... I have a 90 Camaro RS, my driver side door seems to be unrepairable to the point where it gets stuck halfway when I try to close it and almost impossible to open it. Is there a site or someone selling a left side door? Preferable with power windows and red paint? Not too picky about the color at this point...

 

before going through all that have u checked the hinge pins, there notorious for the bushings going bad, most of the sponsors website have new kits available. if you can lift up on the door with it open its hinges are bad

 

look at top down solutions he sells hinge rebuild kits and parts. If its getting stuck its probably the roller detent (which isn't absolutely needed you could remove it to test)-- unless the door is damaged/rusted there i no need to replace the entire door.
