I recently bought my 1986 4runner with 325xxx miles and it is starting to show. One of my biggest problems is that my rear window channel guides have rusted out and i can't roll down my rear window with as all you might now will not allow me to open up the back. The only ones i can find online are for a 90-95 4runner. Will these work for my car or what is the next best thing i can do. Someone please help me.
