The bottom gasket on mine from ERA stuck pretty much straight down before dropping on to the car, so it was deflected forward by the body and sealed tight (except in the little valleys by the posts). Is you gasket formed this way? It sounds like the crown of the body is a little too flat for your windshield. You may have to build up the centerline crown with filler a little (unless your car is already painted) but 3/8 inch is quite a bit. In the little valleys by the posts I did place a ribbon of 3M strip caulk under the weatherstripping there and stick it down with that good. That will probably hold it down to the body but it's not an ideal situation. From the cockpit you will probably see that the winshield frame is not in contact with the body.
