Hi Shane. I will help out however I can but I have yet to install the glass on my pickup and hoping to use the felt over the rubber pieces. Others on this forum can provide more insight as to what goes where. You can use felt strips on your later door and the rubber pieces on your earlier door as long as that difference doesn’t bug you. Most will not notice but if you plan to show your pickup, a judge might. Another difference that may be more noticeable is how the interior panel is attached across the top of the door. There are several varieties in attachment including a different number of holes for the retaining clips, or you’ll have a channel that secures the top of the door panel. One of my doors has the holes while the later door has the channel. This is much easier to address than the window guide felt issue you’re facing. The garnish refers to the interior side of the door, generally a removable trim piece in most vehicles. Early ‘35 pickup doors had a removable garnish molding, which later changed to the non-removable garnish with built in door pull in the center of the bottom edge. I still think a good automotive adhesive could be a remedy for your problem, such as a 3M weatherstrip adhesive, but please ask the advice of others before taking my advice.
Can someone else clarify the placement and direction of the rubber door glass bumpers?
