Hey Marc, what are the actual dimensions you are trying to fit? I probably can't get the Beck Arnley ones, Bud Dad's a distibutor for Cometic, they sell valve seals, but by dimension only (Stem O.D, Gide O.D. and if it's that tight, probably the overall heigth you have to work with for the seal and the largest outside diameter of the seal that will safely fit inside your springs).
