I just learned this week that a stock 4g64 crank with a stock 4g64 flywheel and spacers, requires shimming, at lease in my case where I have a clutch masters fx400 with hd pp. I ended up using a .050" (1.27mm) flywheel shim and put 2.5mm shim behind the pivot ball. Without the shims, I was having an issue with the release cylinder overextended and couldn't add pressure to the pp. The clutch fork was way out of range. I feel like I had to shim a lot, and I will update if I have any issues while driving, but my clutch fork is now in operating range for the release cylinder. This is my first time using a clutch masters kit and I checked the dimensions of the tob and it checked out. I didnt check the pp. As far as I know, a stock pp should be the same for a 63 and 64. Anyways, I was stuck on this for months and after all the research this is what I did and hopefully this helps someone.
Edit: I made sure to use the starter plate, and the spacers, or flywheel adapter plates as mitubishi called them.
The inner(between crank and flywheel) spacer is part number MD754228
Outer spacer is MD760086
Flyweel bolts(7) MD368638 as these are the shorter 15.5mm length
In hind sight, I should have gotten the flyhweel hub milled off the crank and I could have stuck with 4g63 flywheel as there are no performance flywheel for the stock 64 crank.

stroker clutch issue
4g64 crank clutch issue
