I need the measurement from the top of the windshield frame to the top of the rear tub and/or the correct angle of the windshield.

I have a 64 3B with a replacement tub, done before I got it. There are two sets of holes incorrectly drilled for the windshield frame. It does not sit evenly. There is a measurement from the top of the windshield to the top of the rear tub I found years ago for my YJ, same as the CJ7.

I will be welding these holes and drilling new holes, but need advice on exactly where. I plan to get a top for the 3B and the windshield placement is critical for proper fit.

Thanks!
