Usually Nissin M/C bore sizes are marked on the underside.......
Most Hondas use 1/2"
K & L Supply will have the parts kit:
Thanks for responding.
Yes The bore is established at 1/2, but there are many different seal/piston styles that Nissan used in that size.
There are, to my knowledge, no cross references to the select the correct kit for the Nissan master that MV used, Even the photos that accompany the various kits advertised are stock photos that do not represent the actual seal types either.
I BELIEVE that I have found the correct kit number from K&L as mentioned above, and as soon as I can compare them side by side I'll report back.
