    C1: 1960 Windshield Fit

    I installed the new windshield/assy on my 60 and have 5/16 inch gap between the lower trim and the body at the curve of the glass. It fits well at the middle and at the posts. Installed two shims under each post. The lower curved channel that the window and seal sits in is not even squeezing the U shaped window/assy to body seal tightly. It fit very well prior to removal. I checked the archives back through 2001 and it indicates this is a common problem. The suggestion to tap the trim downward with a 2x2 piece of wood is not going to fix it. Does anyone have any better suggestions? I plan to take the windshield assy off but need to determine a correction plan first.

    You probably saw my same concerns in the archieves. I gave up and focused on other items with no regrets. At this point I finally came to the realization that the parts on these cars just don't fit like we expect they should.

      This one fit very good, almost perfect, and I still have the photos. It is like the lower piece is warped???

        Did your lower area between the body and windshield have that rubber filler? I found that installing the windshield back in that the filler corners ( how can I say this) gets turned some times or tilted to where it don't sit flat on the body and by moving it the (tilt) corrected this condition. I've also on some vetts left it out just laying in clay which allowed me to determine how to better move it to fit . The holes in the body and the slots in the bottom retainer bolts allow you to move the window forward or backward plus the rubber shims to get a good fit with the door post. The window post and windshield where adjusted and tightened at the same time in the factory to achieve a good fit.
        How many times have you seen the door post sticking out or gaped??
        Hope this may help you!

          I installed a new rubber filler with the U shape for the windshield to set in. The rubber filler can still be moved under the window curves with a paint stir indicating that it is not tight and that I can move it into the correct position. It is not holding the window frame up off of the body. The middle and the ends of the window assy are about .060 inch off of the body.
          The body holes for the post bolts are snug and do not allow for any movement. Shimming appears to be the only option for the posts. I installed two shims where as it originally had one per post. The frame originally fit the body so well, I can't understand how it can be out so far now. I'm trying to determine what I could have done during the windshield/frame assembling that I lost the relationship. It is a not hit or repaired body, so that should not be an issue. I have owned or knew the owner and history of this car since 1964.
          This is a driver BUT things like this keep me awake at night. It's my nature and I can't accept the fit, yet!!
          Have you ever installed the assy without the rubber filler or were you leaving it out just for measuring purposes? Once the post bolts are inserted, there isn't any movement in the assembly for adjusting.
          I appreciate your response. Thank you.

            I tighten the corners first, BUT I've seen and do if needed elongate the end post body holes to move it if needed, BUT I usually leave the rubber long filler out . I lay in and use clay which many Corvettes did use with the rubber filler. Did you see any clay when you removed it.

              As I recall, there was the aged & hardened rubber seal and lots of soft gray putty material (clay?) that appeared to assure a thorough water tight assembly. The soft putty was entirely in the rubber seal area and did not extend to the point it was visible before removal. The gap between the body and the lower window trim was minimal.
              Currently, the slots for the hold down screws are visible, after I removed the 3M black putty, as if the lower channel piece is rotated. I think any rotation would cause the curved areas to raise and the post areas to lower. This is my thinking at this point. Hard to believe someone has not discovered the solution but I'm going to work on it!!
              The archives indicated others had removed and disassembled their window assy 3-4 times without any improvement. This one is just too bad to leave as is although I saw one at a show with this size gap and it was filled with a sealer.

                Well it's up to you But using clay only and not restalling the rubber seal you will get a better fit,( it's not needed) try just putting the windshield on the body and look how it fits then add again using clay instead of the rubber to seal out water.

                I've seen many Corvette that never HAD the rubber seal

                  That sounds good. I will try it.
                  Thanks.

                    Is it possible that the new glass is a little different?

                      I checked the dimensions a long time ago and didn't note any major difference other then it's over all length. It is a little shorter, hence the glass and seal are short about 1/8 inch from fully seating in the drivers post.
                      The archives noted the short glass issue several years ago.
                      My concern is the contour of the bottom of the assembly does not match the body either in the at rest state or when pulled down. I will try setting it on the body without the rubber seal and if neceassry, disassemble it and start over.
