J. D. --
Wish we had been told that a week ago. Ran with a 3/4 windscreen Sunday morning (after being advised by a genuine Barbee that we might have trouble) and you, and he, were completly right. Lots of solutions in addition to what you offered. Joliffe runs about a 1/4 screen, Barbees run with NACA ducts on tonneau, been told that BRM has holes at the bottom of the front screen. All we know is you're gonna have BIG problems at El Mirage running front and side screens on a tonneau.
