Been working on window alignment on my 68 convertible. Having trouble getting my passenger side window alignment dialed in. The driver's side was fairly straightforward, other than a linkage from the exterior key lock that interfered with the glass (it's a restomod with late model recessed door handles). The passenger's side is giving me a fight. Again , there was a linkage interference issue (I know now why the builder gave up on aligning the windows), which I was able to remedy, but I can't adjust the window far enough up. The rubber stop on the front of the glass is hitting the door panel before the top of the glass touches the top weather stripping. There is a felt covered window guide where the rear rubber stop comes up. Is there supposed to be one where the front stop comes up too? Also, when the rear stop contacts the rear guide, it pushes the back of the window away from the outside felt. Is there a way to adjust for this?
