Windshield mount question

[Ohio Ken]

My older CR windshield shakes upon hitting any and all bumps. I have tightened both outside mounts to the frame via door jamb, access to bolts but still a lot of flexing. This just annoys me to death!
I have notice in viewing pictures of original Cobras, and some of the newer makers, that there is a center mount at bottom of windshield to the dash.
Two questions:

1: does the mount only to the fiberglass dash to wind shield or all the way down to the upper frame member? Any mounting advice would be helpful.

2: anybody know where I can get one?
Thanks

If it is moving around that much it might break it if you try and hold it in the middle or it could be just the fix. Originals just went through the cowl. I would try that rather than trying to tie it into the frame.

Thank you. So I would assume you place it in position, then Mark the holes, then remove windshield and attach to windshield frame, then re-install and place bolts in the cowl?

Yes you can't get a drill under the windscreen to drill the cowl holes so the screen needs removing. The windscreen frame should have the drilled and tapped holes in the bottom center. Usually use a thin strip of rubber between bracket and cowl too.

ERA uses a center windshield bracket and you might be able to get one from them.
Whatever you go with pay heed to the horror stories about windshield frame screws cracking the windshield. Make absolutely sure the screws in the frame don't contact the glass when the windshield is in the frame. A careful fitting of the bracket to the frame should do it.
The ERA cowl is heavy enough to use sheet metal screws. If you order the bracket from ERA ask Bob what size they use when you order it.
Pre fit the windshield frame without the glass in it but the bracket attached. Check that the bend angle of the bracket is correct and adjust if necessary. Mark, drill and screw the bracket to the body. That way you won't have to be letting the screws create the threads in the fiberglass at the final assembly. On final assembly you can turn the crews counterclockwise and feel them align with the preformed threads. With the glass in the frame you'll have very little room to work. Harbor Freight makes a neat little 1/4 drive ratchet with a set of 4 bits that should get the final mounting done with a minimum of fuss.

Could part of problem be flex in structure such as seen when going over bump at angle? Or crack in substructure for example. Frame flex?

No it is just the windshield, you can flex it slightly by hand in the middle just enough movement that it shakes when you hit bumps. Yet nice and tight toward the outside edges. It is not loose just a bit annoying on some of these ****ty Ohio roads..
Much better since I read about tire pressures on this forum. Tires had 37psi when I bought the car.mlowered the front to 25 psi and the rear to 27 psi. That really improved the ride and shakes . Might even get better when I install all new bushings in the suspention, and switch to coilovers.
