(See pics). Putting back together a '74 Merc 500 motor (50hp). The upper shim on the crank (part# 15-20085A 1) is an NLA, but I got the entire set through an NLA vendor. Thing is,the kit has several shims of various gauges. Like an idiot, I threw away the original shim to compare the new one to. Which one of these do I use? THANK YOU.
