Example: A 1972 Chevy truck, the windshield in those trucks when they were brand new were almost 1/2" thick. Fast forward 15 years after living in the sun all its life. the gasket is hard and you want a new windshield installed. A new windshield is now probably 1/4" thick. You can install the windshield in the gasket but you will never get the old gasket to seat to the new windshield let alone be able to seal it up. Smell what I am stepping in if I am understanding you correctly??
Sealing the windshield is all done with the glass installed and having the stainless off will make it easier. I have installed rubber set windshields and applied a ribbon of 08509 bedding compound to the gasket and then roped it in, but it makes a huge mess and you dont get as good a seal if you were to just install the windshield and then cut a medium size tip in the 08509 and shove it down between the w/strip and windshield frame and pump it in until it starts coming back up at you and then you can paddle it in with either your finger or a plastic windshield installation tool(the 08509 does not get hard).

After looking at this pic. I smell what your steppin in now. Providing that nothing is wrong with the windshield frame, I would get a new gasket. This is my windshield and gasket. Its a Pilkington and a Corvette Rubber gasket. Once I seal it up and install the moulding and the sunlight does it's thing, it should be jam up jelly tight. I took one with flash and one without.

Well I think that I have determined that the glass is two big. It's a PPG glass so does anyone have a recommendation to what has worked? Is the Pilkington the same as PPG? Thanks..

In my post,#2,that's what I was assuming. On my rear glass,after several Pilkington, and PPG,I believe, I finally got one that fit very good the first time. It was OEM glass. Believe it came from CC. OEMglass.net

I installed the glass again with a different weatherstripping since I had it. Same result. I guess I'll be ordering ANOTHER windshield. I'm ready to put this thing back together so I can drive it again.. I'm going thru withdrawls!!

Sounds very frustrating Dave, one step forward and two steps back. You do all that work, spend money on new parts, and the aftermarket parts don't fit properly. I know you're ready to get the mighty mouse back.

Once I get the windshield set properly I can move one to putting the interior back in and get this ole girl back on the road! It was good seeing you last week BTW.
Once it warms up William and you need to come see me so you guys can take the Cobra out!

Sorry to hear about that Dave... I was hoping after seeing it that the gasket could have been rolled more to the outside as you hoped.

I used Pilkington glass last spring and it fit just fine. I purchased it locally from a wholesaler for ~$99. Got the weatherstriping/clips/screws from Paragon. Was not my favorite job in fact probably my least favorite job I've done on the Vette.

George, from reading your write up it appears we both have had some trials and tribulations to get our glass set in properly.
Something to add I made up a soap solution and forced it into the glass lip and the lip for the birdcage. I did this so that I could slap the glass and move it around once I had the glass installed. It allowed me to determine that no matter how much I beat on it that the glass was to big and the weatherstripping would not lay down right.
The bedding / glaze is a mess for sure, it does clean up nicely if you get some of the adhesive remover from 3M though.
I guess I'll have a reprieve from the 66 today until Monday when I can see if I can get a Pilkington windshield.

Yes, believe it or not. You already have a belt sander?? Either check your local friendly glass shop and see if they will sell you some 80g(will remove material very fast)belts and some spray can lubricant. If not, you can check www.crlaurence.com and see what it would take to get a couple of belts and lube. I can post up a picture of a sanding belt if you need also. If nobody knows what to use for the lube, you can also use water but it has to be continuously sprayed on.

Thanks, Yep got a belt sander that I use for my wood project and I believe that I have some 80 and up grit belts. That maybe the route I have to take.Is there any concern about the laminate and sanding? Also will I need to polish the edge when I get done for it to not cause any problems with the clarity of the glass in the areas that I sand the edge?

Ah see in my quick reading of you post I missed the part about "glass" sanding belts. I'll have to look for some locally tomorrow. If you have a pic of the belts handy it would be nice to see what it looks like. Thanks

Yes, you need glass sanding belts. Dont forget the spray lubricant for them also, DO NOT SAND DRY!! A picture will be coming up in the next post or 2 for you.

The picture is of 2 80g belts. Inside of the 1 it says 'sil carbide cloth'. What they are actually made of, that I dont know. Like I said, the lubricant will keep the belt cool cause if it gets to hot, crack. If you have an old windshield or can get one, even a piece of laminated glass, practice 1st. I personally think you can do it after looking at some of the things you have done so far. Just keep that belt lubricated. As the belt wears, especially if you use a 180g, it will make a nicer edge.
