I have ordered it from japan
my JDM caps says:
MD346741 2000.12.1 - 2002.11.3 ALL <
MN155760 2002.12.1 - 2003.12.3 ALL <
MN158470 2004.01.1 - 2004.12.2 6FM/T SJGFZ < EVOLUTION-8/8-MR/9/9-MR(GSR),6

I`ll be glad if someone share exact size for other evo gaskets in form "part number x bore x thickness"
also interested in stock sizes of 1, 2, 4, 6, 6.5, 10 EVO pistons
