Well I bought the new vent window frames for my 69 post car runner. Have had to drill and neural the holes where the bolts hole it in the door. The driver side is giving me a fit trying to align it up. Took part of my thumb off to day pulling out the door plug. So I could get to the adjustment bolt's. It is too tight at the back or could say to far back. Just can't seem to move it forward. Top is not going up far enough to close the gap to the gasket under the drip rail. I adjusted the bottom bolt but now to high on the vent frame so going to lower it. Will have to drill out the hole in the bottom fork on the vent window so it will move forward and not be to tight on the door sill its self. They just don't make it easy. Has any one had this problem with the window being to far back towards the post.
