i have a th350/203 adaptor that i'll be using. i was wondering if the seal on the adaptor could be replaced, as the one currently on it is beginning to tear off. any part #'s if they're available? i went to autozone this past weekend and the guy looked at me blankly and said they didn't carry it without looking it up or even trying to help me in some other way. i even tried asking him again and told me no shaking his head before i could even finish...yea great customer service.
