    you can only buy a longrod piston up to 68mm.anything bigger than that you have to buy a sr piston and use the spacerplate.

    This was the kit I was thinking I needed because it’s the same part number that was on the old piston

    I suck at Motors so I'm not much help. ESR racing has the gaskets and seals you need. 3 day shipping usually.
