I don't remember the number. They both look the same to me. Update: I did have a major storm blow in. Water pooled big time....but that 303 spray did the trick. No leaks.@BroncoRox @Geo - do you recall the correct part number for the 2-dr cockpit cover? Ford Accessories lists it as VM2DZ19A412B but Lasco Ford (who has it cheaper) lists it as VM2DZ19A412A.
