Rodger, that split metric and sae stuff drives me crazy. I had a GMC Suburban that required both and younever knew which one you weregoing to need until you tried it. With the 3 wheeler i suspect only the engine would require sae wrenches.
With the good previous suggestions i found a Thread that had a wealth of information on parts and ideas.
I was unaware that Japanese Phillips head is different than the rest of the world. How does it differ? Blade thickness, width and depth?
