well, i got a new set of glass for the 40 and a new seal, attempted to get it in yesterday and successfully got the driver side in and cracked the passenger side... i will be ordering a new passenger side windshield Tuesday and am wondering if it is possible to install it with the driver side already installed? or will i have to remove the driver side? hopefully those of you who have done this have some tricks or tips for me!!!! if anything could those of you who have done it give me some steps to use for the install on the '40 merc style windshield? thanks in advance!

If the 40 Merc is like the 40 Ford you install both at the same time. The glass fits into the gasket and then the gasket is "roped" into the cavity from the inside. It's a two person job and you do not use any pry tools to get it into the opening(pry tools break glass).I recommend that you take it to a glass shop or get someone to help who has experience installing glass. This is not an easy job for a novice.

I had the same problem in 2004. When I took out the new glass and measured it against the glass that I removed, it was about 3/32 larger across the height. I had the new glass cut using the old glass as a template. Another reason for the glass breaking is rust in the opening. Make sure that the opening is clean and covered with paint. I have not tried to replace just one side, but I believe it could be done. Be sure to use a lot of liquid soap or a rubber lubricant on the gasket and use a sturdy twine to help pull the gasket though the opening. Make sure that you seal the gasket around the body and glass after it is installed. I used the flowable glass sealant available at most auto part stores. Tom

agreed it isnt an easy job.... i actually followed the instructions per bob drayke's seal that i bought, then when that failed i followed the instructions in an old origional shop manual that i have.. i guess the key is just taking my time!!! and not using any pry tools.

Installing new windshield glass depends on the glass being the right thickness, the cutting pattern being correct, and the gasket being the right one for the car. We have run into problems with all three at one time or another. The common way is to install both sides of the glass in the seal, run a strong cord (we use nylon) in the groove that accepts the body flange, and liberally apply dish soap (we use Ivory) to the cord and groove. Set the whole assembly into the opening from the inside, seeing the the seal is all the way down over the flange. While a helper holds the assembly up into the opening, work the seal over the metal by carefully tugging the cord out of the groove toward the front of the car. When (not if) you find a spot that resists tugging, use a tool, such as a screwdriver with a bent tip, very carefully work the rubber out. If you bear against the glass, you will almost certainly crack it. Once you have the windshield in place, we mask around the gasket with masking tape, and insert a good quality sealer, such as 3M, and wipe off the excess. You may not need the masking, but we find it a whole lot easier than using a solvent. Don't try the job without a helper, and take plenty of time. And, as said above, be sure the metal flange around the opening is clear without any burrs or kinks before you start.

ok well, i went out this morning and took out all glass and compared it with the original, and it is not the correct size, height wise. i sent the origionals and the new glass to my glass guy to have him cut the correct size... hopefully it works better the second time around. thanks for your advice guys.

Obtaining the correct size and thickness of replacement glass is a problem today, when most glass is the tempered variety instead of the laminated safety glass. If fact, many shops don't know how to cut the old style glass, let along cut it to the right size and correctly finish the edges. Places that furnish old glass may seem expensive, but there is a reason.

i got it through a place called the glass house in California, ive gone through him for all my glass on the car and he has cut everything exact and ive been very satisfied with his products, except the front windshield glass... but he is going to trim the glass down to the original for free and compare the two for exactness. so its not a big deal. except for shipping =\

hi 40 MERC if you use 3M blackwindshield sealer, if you get it on anything USE WD 40, will not harm the paint,and gets the job done quickly,and have a lot of bounty paper towels,have a roll ready, and you can go to a place that repairs chainsaws, the pull rope they sell in different sizes and works great for installing the rubber gasket windows, my 3 cents worth 37RAGTOPMAN

Always measure the thickness of new glass with a digital caliper, or similar tool, after determining that the new glass is exactly the same shape as the original. Glass breakage during installation is almost always due to trying to force the pane in place with a tool of some sort. Even if you do succeed in getting the oversize glass in place, there is a good chance that it will eventually break from stress or contact with the body opening.
