Just picked up a 90 4runner and the rear hatch wont open because the window wont go down to allow it to open. The entire inside of the rear door has rusted parts. quoted $1000 to get new door from guy in arizona... too much. Where do i go to get replacement parts, or is there a way around replaceing everything that will allow me to open the door. I dont need the window to open, only the rest of the door. Apparently this is common among 2nd gen. anyone else with this problem with a solution? Thanks ~ Andy
