| − | You can install windshield glass in most any car that had a windshield frame or rubber molding using the S-10 filler strip and an adhesive as long as the pinch weld is behind the glass. | + | You can install windshield glass in most any car that had a windshield frame or rubber molding using the S-10 filler strip and an adhesive as long as the pinch weld is behind the glass. Some prefer to use urethane or silicone instead of butyl tape due to the irregularities in the flange or pinchweld that backs up the windshield. |
The basic procedure is to get your pinchweld all cleaned up and any voids filled. If there were slots or notches for hinges etc they need to be filled. Obviously rust and loose paint needs to be removed. A coat of epoxy primer is a good idea. | The basic procedure is to get your pinchweld all cleaned up and any voids filled.

| − | Have your glass cut so that you have about 1/4 gap between the edge of the glass and the windshield opening. No more than 17/64" and no less than 15/64" gap all around. | + | Have your glass cut so that you have about 1/4 gap between the edge of the glass and the windshield opening. No more than 17/64" and no less than 15/64" gap all around. Always trial fit the filler strip before you do the install to make sure it isn't too tight or loose. Too tight and the glass may crack or pop out during installation and too loose and you will have gaps. |
| − | You can paint a uniform band around the edge of the glass with Dow betaprime 5500 pinchweld primer. This material will create a dark band around the edge of the glass similar to the baked on ceramic frit you see on most all of the newer cars. Mask off 1/2"to 3/4" uniformly around the edge so | + | You can paint a uniform band around the edge of the glass with Dow betaprime 5500 pinchweld primer. This material will create a dark band around the edge of the glass similar to the baked on ceramic frit you see on most all of the newer cars. Mask off 1/2"to 3/4" uniformly around the edge so the glue line will look good from the outside. Mask off inside of the frit line so as to have a nice line to cut the setting adhesive to. Tape off the entire inside of the glass to protect it from scratching and excess glue. |
Position the glass so that it is flush with the body using at least 6 rubber setting blocks 1 in each corner and 2 in the middle.. You want the glass to sit evenly on these blocks .You can maintain your 1/4" gap with some scraps of filler strip or wooden spacers, removing them as you install the strip. | Position the glass so that it is flush with the body using at least 6 rubber setting blocks 1 in each corner and 2 in the middle..

| − | Once the windshield is positioned | + | Once the windshield is positioned, Optional step: You can dry fit the filler strip.. You can make a butt joint in the middle of the strip at the bottom of the window. Try to not mitre corners unless you absolutly have to because it is very hard to keep the edges down. The strip can be notched on the inside of a corner to make a tighter bend. Practice making corners on a scrap to see how it works. Once the strip has been dry fit you can install it permenantly. When you install the filler strip use super weather strip adhesive on at least one side of the strip. Glue the ends with super glue. Once the filler strip is installed backfill the space behind the windshield with urethane adhesive, tool it so it looks nice and has no voids. You should have at least 3 full size tubes of adhesive ready for your install. Let it cure and you are done. |
That is a fairly simple set of instructions, there may be other things that need to be considered such as what to do about your dash and header panel, etc. Is the windshield 2 pieces? this may require a center seam. | That is a fairly simple set of instructions, there may be other things that need to be considered such as what to do about your dash and header panel, etc. Is the windshield 2 pieces? this may require a center seam. | ||
