Alan, Got your instructions thanks... Here is what I have done..
I put together the Windshield. Placed in on the car with masking tape all around. I stenciled in the windshield lower rubber to ensure the window was center and even. There was a small gap in the center rubber mount, but other than that it seemed to fit perfectly. I measured from there back to the posts.. measured the from the Wiper Slots back 1/2 inch.. The windshield seemed to fit perfect, other than a small gap in the center.
Then I measured your markings... it lined up perfectly. Then I removed the windshield and cut all the holes.. center and posts..
Then I placed the lower trim on at 1/8 inch back from outer line marking of lower windshield rubber.
Then I installed the Lower Trim on the new line and pop-riveted in place. Now I need to install the upper parts of the windshield rubber and trim and mount completely... I have some concerns though.
The Lower Rubber Mount appears to install on the Lower Trim piece, but what holds it in place for security and safety? Is the center post and end posts enough to hold in place? Seems not very sturdy or sound.. perhaps I am just nervous. Does that gap I noticed in the middle just have to do with the fact that the windshield does not really sit on the car but on the trim and the gap is normal.. that gap was about a 1/16".
Thanks
Brian
