Don't have a clue. I took the two that were on the engine I took the coil and dist off of.
I would like to add that if the seals are leaking and they likely are, you can put a special washer on them. I found an aluminum washer with rubber molded to it on one side. They were at OSH(Orchard Supply Hardware) in the hardware bins where they keep odd fasteners, bushings, pins, etc.
