Is your 67-76 A-body windshield leaking ?
Gasket has a groove that slides on to the rail.
So, I went and opened my seal, WCR D690 for 68-72 A-body excluding Duster.
Exterior of gasket has a tongue and groove along the sides, and the top and bottom corners are completely open.
Any water that gets in will drain out the bottom corners.
The bottom of the gasket has a groove for the bottom rail between the cowl drain holes, separate from the rest of the gasket, last pic.
Problem is, there is no bottom raised rail on the car.
If water gets into the groove on the top/sides of the gasket, it appears the gasket directs that water to the cowl drain holes.
Why is there expectation that water will get into the groove on the top/sides of the seal, and therefore need to drain, but not into a useless bottom groove?
Why have a bottom groove that has no male counterpart?
Why design it so water can easily get under the bottom into that groove and have nowhere to drain?
With no sealant, it just looks like those drain holes could easily become overwhelmed.
This stuff is excellent for window openings with rails or walls or the pinch welds where panels come together, whatever you want to call it.
