[C2] Front window run re-install issues





1. The long vertical part of the ventilator assembly attaches to the vent frame with 3 small (about 3/8") screws, one through the bumper at the very top, the other two about level with the top of the door. That's these two parts, in case I'm using the wrong terminology:
My problem is the two lower screws don't seem to engage the threads when I try to install them. They are supposed to go through the blue holes at right and screw into the blue holes at left. The rubber of the vent glass sticks up slightly but I can press that down as I'm trying the screws to where there is no interference. So questions here are A) why won't the screws reach the threads, and B) since it's attached to the door at the very bottom, and to the vent assembly at the very top, and has the window glass holding everything snug, is it critical they are installed? I'd prefer to put them in because they "should" be there, but occasionally the prevailing wisdom is "skip it".
2. The glass run channel with fuzzies attaches to the tall vertical channel with two rivets, one at the red arrow in that pic and the other way down at the bottom. The rivets remained when I pried out the old channel, I will drill the old ones out. The new strips don't have holes, I can drill them if necessary. Any reason I should not put a nice bead of black 3M weatherstrip Adhesive along there instead of rivets?
(I don't want to "bubba" things up to where they don't operate right, but for where I'm going with this car, there's no need to duplicate the factory work if a reasonable alternative exists.)
Thanks!
I just completed this same operation on my 65. The two screws into the vent frame are needed. The threads may be stripped out so you have two choices. You could purchase longer screws that would go deeper into the frame and grab the threads deeper in the hole. OR go one size larger on the screws and tap out the frame holes to match the new screws. I went with a longer screw and it worked for me. You could try filling hole with JB Weld and then drill and re-tap the hole to fit original screws but I have not had success with that method.
The window run fuzzys are supposed to be riveted into channel but most people will use small screws and nut on outside OR use epoxy like JB Weld to glue the fuzzy into the channel. If you go the epoxy route you can use the rivet holes to secure the fuzzy into the channel with a screw and nut while the epoxy sets up and remove later. Good luck on your project!

Once installed, the vents are not tilted reward enough for a uniform gap at the A pillar. I still need to adjust that. Otherwise it’s straightforward.






Those small screws are self-tapping it appears altho a slightly longer replacement might not have to be. I'm headed to the garage to bring in my 3 coffee cans of loose unsorted screws, and a large broiler pan to dump them into. Maybe I'll get lucky and save a trip to the big box store, I've been battling a nasty cold etc for over a week. Negative on the COVID test but it's taking a long time to leave. I figured just work on some of the Corvette stuff I have in the basement, what could possibly go wrong?

I still have the old style straight ones if you need them getting ready to throw them out FREE

Don’t waste your time with the straight weatherstrip. I have a couple free too





I have not done anything with the car for a couple weeks, staying at the house and have been working on the '66 truck project just because it's right here. I need to re-focus on the Vette, we're overdue to spend a few days out there soon.





Which vendor did you buy the curved run from?

I ran in very short course thread small screws and they bit.
I riveted the front felt track over them and all back together.
The pot metal frames will rethread easily. You run the screw in as a self tapper as I did or tap it out.
