Default Lower Windshield Frame / Front Clip Seal Question

I recently replaced the windshield frame on a 69 Stingray. Now I have a 1/2 inch gap between the windshield frame and the front clip. Any idea how I can seal this up ? I definitely don't want water in the cab in the future.

Hi cvr,
I've looked at your pictures and can't figure out what's happened. I guess the only thing to do is bond a strip of fiberglass on top of the void.
Regards,
Alan

If I understand what I see you have gap between the upper fire wall to the lower windshield frame, those two parts should be rivet together with seal between them.
My guess is: the windshield frame wasn't weld correctly or the front clip sink at the front.

Something definitely isn't right here. Probably not what you want to hear but I recommend pulling the firewall and reinstalling it so that the flange of the firewall is tight to the windshield frame. Yes, you can probably fill the gap with filler, adhesive, or fiberglass, but with no structural connection (e.g. rivets) it will likely crack and leak over time. Lot's of water comes over this area so you want to be sure you have a really good seal.

Is the front clip attached? I wonder how this may affect fit-up and alignment of the front clip...

if you can look in door jam area to see if the firewall is pulled away door pillar.it looks like the rivets are not there.my firewall had a gap on the right side but once I repaired the cage everything fit.I used 3m panel adhesive pt 8115 it will bond fg to steal

I decided not to tackle the fiberglass. Trying to replace the rivots and seal it up good looked like a little more than I wanted to get in to. Instead, I put 1/4 inch of 3M Windo Weld window sealer. That stuff is very tacky and was very difficult to put in place, but I got it in there. I then put 1/8 inch of 3M Windo Weld, super fast urethane on top of that. It felt pretty solid, but only time will tell. Here is a picture of the finished seal and the 2 sealers I used.

Looks like you found a way to deal with this. On my 68 I replaced the whole frame also and had that gap afterwards maybe not as big as yours though. I think the glass just bows and pulls away natuarlly maybe not but my thought. With that I used screws and nuts on mine and the glass pulled up to the lower frame just fine, I then went back and one buy one pulled a screw and put a rivet in, and of coruse put sealer in before all this, came out looking like it should,

Hi MA,
Nice explaination!
I would think (as you describe) that that gap would have to do with the cowl fiberglass and not the front clip. Maybe the clip was mentioned just in passing?

Alan
