I am in the process of painting my 70 Chevelle & was trial fitting the trim around the windows. Seems like the glass might be a little low in the channel. Does anyone have a car without the trim they can get a distance as to how far down the glass sits?

Thx.

It should sit about even all around. If it sits to low you must have forgot to put in the rubber spacer blocks on the bottom. These keep the glass from sinking down over time due to heat and gravity. If you forgot them, pull the glass and redo it now instead of later.

It has the rubber blocks. it's not low in that dirrection. I think it is actually "sunk down" towards the interior. Looking for that dimension.

Front glass has two clips rubber coated on one end that screw into the upper part of the cowl. These hold the glass at the proper height. About an 1-1/2" long by 1" wide. The rear glass should be even all the way around. Temp. 1/2" wood or rubber spacers help to hold the glass in place until the WS adhe. has set up. Then pop them out

I'm not sure everyone is understanding my problem. I am thinking the glass is sunk in the channel slightly. Maybe the butyl tape is too thin? I am looking for a measurement from the face of the glass to the face of the car. I am tyring my best to explain this but it's dufficult. The glas has an even gap all around and the rubber blocks are in place.

Allwhite,
If you are using butyle(sp.) tape it comes in two sizes for our cars,3/8 and 5/16 depends which glass you are using.Old glass is thicker so use 5/16 tape on it ,new glass 3/8.

When I dry fit my glass and molding I used a paint paddle cut into small pieces 1/4 by 1/2 inch, stacked three together with tape around them to get the 3/8 inch thick. Set the windows on four of these blocks, then fit the molding. It was a little higher than the butyl tape but was close.

Yes, That helps. I am not near the car but will measure it when I get there. I am guessing I could put a paint stick in the glass & it should be flush with the body or a little high.

I asked this same question a couple of weeks ago - no answer.

How hard do you press down on the glass with new butyl tape when you install it? Just until the butyl shows on the glass? or squeeze it out some both ways.

I would think that how much you press down will change how deep the window sits in the channel.

When you set it on the butyl you press in the center of the glass and not the edges. Esp not the upper corners because you can crack the corners of the windshield. Once it's in there you should see at least 3/16" of contact all around. You will not beable to squeeze the windshield down to change the height of the butyl tape. I've got a feeling that you used the skinny tape when you should have used the fatter butyl tape.
