Default 1974 pop out window question

Hello All…

Still going around with trying to get this damn weather-strip in for the pop out window… well it's in but the window doesn't want to fit in it.

I gave up on this problem last summer and just drove around all summer with the window out - but I would like to be better prepared for random storms I may encounter…

ANY tips?

Thanks!

Put your adhesive on the weatherstrip and put the window frame in to hold it in place.

Hi,
"but the window doesn't want to fit in it" describes the problem, but doesn't give us a lot to go on.
Maybe some pictures of the weatherstrip installation?
Regards,
Alan

74 rear windows did not pop out. Have you converted to the 68-72 style?

The rear back glass were sealed in place with butyl tape...originally.

I have converted to the pop-out window as I found a great deal on the glass last year. I have all the brackets, hardware and roof panels for the project - just can't seem to get the glass to fit in properly with the weatherstripping installed. The bottom of the window goes in just fine - the top doesn't seem to want to go into place as the weatherstripping seems to thwart it from doing so… but so far as I can tell it's installed correctly… I am trying to attach photos but can't seem to do so…

Anyhow the weatherstripping is up as installed as high as it can be on the roof; window seems to catch as well in corners - mainly the driver's side…

I am trying to avoid tearing the whole thing out and starting over… anyone else have this issue?

If you have installed the pop-out back window of a 1968-1972...and EVERYTHING was installed...You should be able to set the lower guide pins in the frame in the correct points on the body and push the glass into position and then the tension clamps used to lock it in place an seal it as designed. IF this is not happening...you need to get this correct first..and also you more than likely know....the clamps may need to be adjusted.

Hi 74,
Is it possible that the lower receivers (either the metal or nylon parts, or the screws) aren't installed quite correctly in the sill and are preventing the window's frame from sitting low enough to let the upper corners move into position?
Or may the corners or the rubber seal not be pulled into the corners (upper or lower) to let the window frame seat properly?
Regards,
Alan





Note 3 flat head screws holding corner in position.




Note screws.

Thanks for those pics - those are helpful. Were there holes already there on the body or did you drill those holes?

I'm hoping to get out to the garage today after work and I'll investigate some more... Is there a way to adjust the brackets on the window itself?

On an semi-unrelated note - how do you post pictures on these threads? I wanted to post some of mine to help illustrate the issue...

Thanks so much!

Hi T,
The holes that the 2 pegs on the bottom of the frame slide into were cut on 71 cars…. probably (?) not on later cars without the removable window.
There aren't holes for the 3 screws on each side of the upper corners..
Are the 2 pegs on the bottom of the frame properly? It's possible to put them on backwards.
Regards,
Alan

Thanks for your response Alan - I'm not familiar with the photo sites I am accustomed to just uploading straight from my computer - so thanks for filling me in haha.

The 74 has all the cut outs etc needed for the windows beneath the roof panels etc - all I had to do was get the hardware. I suppose the brackets could be on backwards... I highly doubt the individual I bought the glass from ever messed with it as it was factory on his car and he forgot to sell it with the vette years ago... But I suppose stranger things have happened...

Alan,

It seems that the window is catching on the bottom ledge… if I put the two posts on the bottom of the window into the slots and try to press the window forward into place it won't go past a certain point - as if the bottom of the weatherstrip is preventing it from going forward enough… I could drill out the slots in for the posts a little but I would like to avoid that… It looks like in your picture you have two little guides that form a channel along the bottom sill - I don't think mine has that - what year is yours? perhaps those are elevating the window slightly?

ding!ding!ding!ding!

If you purchased a weatherstrip for the '74, it may not work with the earlier window conversion.

Yes I am using the aforementioned years weatherstrip. 1974 used butyl tape for the seal.

Hi 74,
The pictures are from my 71.
All I can offer is that the window frame DOES need to sit low enough or the TOP of it hits the halo trim as you tip it into place.
Have you tried putting the window in place with the posts removed from the window frame?
That might tell you if they're preventing the frame from sitting low enough, or if they're hitting something as you tip the window rearward to latch it at the top.
There's VERY little help in the AIM for the window installation.
Regards,
Alan
