1ST Gen WindShield gasket

I used the 65 pick up truck gasket on my 65 van. It was an aftermarket part number, I can't remember now.

It did seem to fit onto the glass a little sloppy, But once installed into the frame in settled in under compression and as the next few days passed it all settled right in nice.

That picture looks like it could be the same as my gasket but I didn't try it on the fram first.
Try putting it on the glass and see what thats like.

It looks like you have about an axtra inch or more but I think you could spread that around the frame evenly under compresion and it should fit. I wouldn't cut that.

My windshield was installed with the rubber on the glass and sat in at the bottom. then pulled in up both sides and across the top using a string and well soaped up rubber. Some time after that it settled in; then that black butal rubber caulking was put into the rubber from both the glass and metal sides. to seal it, messy but has to be done. Some install the rubber and windshield with the cualking all at once but I think that would be real messy, and it might glue down defor it settles into place.

OH ya, soak the gasket in medium hot water first.

picture comeing

you can see here how loose it fit the glass. Look at the left side. It seemed to be too big but once pushed into the frame the rubber compressed and spread the extra around evenly and it fit nice.

Thats glass guy who said it will shrink a bit once the sun is on it, if it has a split, that will open up.

Put the bonded joiont at the bottom center.

Just what M1D said.
I installed gaskets in the `65 GMC & `66 Chevy without cutting.
Take your time.
Move the gasket around the glass so that the "extra" is even.
Soap & rope works the best.
Don't forget the 3M bedding compound !
Lay the gasket in the sun to make it flexible.

A friend of mine (glass guy) installed mine with no cutting. Bill

I used GM # 3794940 which in the 1958-65 GM truck book shows :
1964-65 all exc cowls, g-10-g910, P models exc deluxe equip (no molding)
group 16.040

Don't know what to tell you.
Had no problems with the gasket or install.

There wasn't that much extra gasket on mine ...

Im wondering if you are running into the same thing I did ,, the windshield you are replacing may have been cut to small in the first place if its not original., I had some numbers written down somewhere , but 59 and 1/4 inches diagonal comes to mind for original glass ?? maybe ...

I can measure that,,,,,,,but it still dont fit in the frame,,,,,,here is another one that I had to cut,,,,,,,,,,I am wondering if the 60-63 pick up gasket is any better or if they are mixing them up,,,,,,

That does look too long.

Mine was an aftermarket gasket. Started with W in the part number but I don't think it was the number you have. As I recal there is another very simular part number from the same suplyer for the 2nd gen gasket.

Your gasket is so long I now think you might have the 2nd gen one.

There is a proper bonding agent to re seam it if you are going to cut it down.

I will look for the paper work on the gasket I used and repost in a minute.

found it "corrected numbers below"

I used the WBL653 gasket which is for the 64-66 PU.

The WBL693 is the one that fits the 2nd gen van and many glass shops and parts dealers try to say that 64 to 70 Chevy is all the same windshield. Thier parts books are clearly wrong. Some supliers use WCR653 for thier 2nd gen WS gasket!! look at those numbers, it would be very easy for them to mistakenly send you the wrong one.

I think if you google that number you will find the suplier. Its not expensive as I recall it was $43 CND shipping and all. I think that means its a $27 gasket to you guys.

I bought mine from classic parts in riverside mo. was a little long
but fit very nice once installed it was only 29.99 plus shipping.
was a gasket for the 66 non deluxe model.

on that list I showed earlier. They show "G van 65 to 70 WBLD693"
Thats not correct for 64 t0 66 G van

BUT they show "GM truck 64-66 take a WBL653 for standard no crome insert or WCR653 for the custon PU with crome strip.

This list is fron the "Wheatherstrip Connection" where I bought mine from.

I used the WBL653 and althought a little loose it went in nice no cutting. I don't know who the suplier is but I do think it was Precision and that that is thier part number.
