I just bought a 89 rs but the doors are rusty it has manual roll up windows. I found 2 doors with no rust on them but they have power windows. Can i convert the power doors to manual using the parts from my old doors. thanks

 

yes youd need the window regulator from the old doors and the door panel so the window **** will go on. You may also want to consider maybe buying a center console lid with the window switches and converting to power but its up to you. Its a pain in the *** sometimes to change window regulators because you gotta drill out some rivets.
