I’ll be replacing all my weatherstripping at some point as well.Worked on fixing the vent windows on both of our early-style front doors on our 1970 40 series. The little metal stoppers that keep the vent window from opening too far weren't put in when I assembled the doors a couple of years ago. That was a very dumb mistake on my part because the doors are so much easier to work on when they are apart and laying on a flat surface. Anyway, the challenge was to try and insert the metal stoppers and nylon washers without removing the doors or totally separating the top half from the bottom. (I didn't want to remove the weatherstripping) After removing the vent windows, I was able to raise the top frame enough to expose the inside bracket for the vent window and carefully insert the stopper and nylon washer. Then reposition the vent window so that the stud indexed with the stopper. Then re-assembled everything. The first go-around the vent window didn't open very far before hitting the stop. So I took everything back apart and flipped the stopper. Now the vent windows fully open before hitting the stops. (I'm not sure if this is correct but they seemed to work okay) I also tightened the retaining nuts to put more pressure on the springs so hopefully the vent windows will stay in position at highway speeds. Also, applied some Bob Smith Maxi-Cure to hold the bottom of the weatherstripping in place. Finishing touch was installing a pair of City Racer hole covers.
