Windshield measurement with body

[Rus Curtis]

Sounds good to me.  The latches can serve as a "fulcrum" allowing the w/s to pivot where it best sits. 

Either, 1) be sure to keep the bolts at the pivot brackets loose or 2) unbolt brackets from cowl but leave attached to arm and set the w/s to see where the holes "should be" (this is a replacement tub, right?). 

Also, cross check when you get the clamps to appear vertical to see how close you are to the 66.5"

Thought of an additional place to look.  This image attached shows the holes in the instrument panel for the Windshield Clamp Catch on my 3B.  I'm not sure, but would like to assume you should also have slots - for adjustment - on a 3A/MC as well.  This would need to be verified by someone else.

THAT PHOTO IS INCREDIBLY HELPFUL!  I got frustrated and drilled out the spot welds in the plates on my repro dash with that rib for the latch catch to grab.  I need to lower the slots about 1/4" on both sides.  Your photo shows the plate / rib about a 1/4" below the lip of the body attach to the dash or that is my observation.  I have not reattached my plate / rib as yet but it will likely be much like yours!  Thanks, that photo helps me confidence a great deal!

Also none of the reproduction cowl/windshield gaskets are accurate. I bought 5 of them from different sources looking for one that fit a 3A/M38 frame and none of them would allow the windshield to fit where it should. Original tub and frame.
