Do you have half doors or full doors? But I got weather stripping from the junk yard for about $5 and got alot more than 10ft but for the sake of keeping it simple just get it from O'Reilly's. Just get a strip that's in similar size to what the kit has and use it where the kit uses it. It's not hard, just put weather stripping where you can, which is mainly going to be on the front windshield, the openings for the doors, the back window (top of the tail gate mainly) and depending on how good your top fits you might need to do double layers of it as one piece on the jeep and another on the top so you get a good seal. Tape does wonders weather masking tape on delecate surfaces or duck tape on stronger serfaces, it doesnt look good, but it sure does seal.
