Just a quick note on the Brookville stanchions, I just received a pair of their stainless, 2" chopped, stanchions, they're in Brookville blister pack, so I know they are Brookville's. They don't have what I would call a "lip" that would stop the glass. There is an insert piece welded on the inner side, that has a groove stamped in it that might "catch" the side rubbers, but that would be the extent of it. Hardly what I would consider a "lip" worthy of stopping an installed windshield. Certainly not like the actual lip on the inner edge of the stanchions on my '36.
