any ac plug with a t in it stands for tapered seat which does not require a gasket and will not seat properly in early heads. i havent been able to find r44 or r45 plugs. can find r45s. the s stands for extended tip which means the shell doesnt shroud the tip. so stay away from a plug with a t after the number but any number alone or with a s after the number will work.
