I've got a motor for earlier than 65 so that might fit your buddies, i bought it in error before i new about 65 only.
i decided to go down the 66 route as it seemed to be the nearest/neatest alternative, i'm just awaiting the few bits i couldn't find second hand to arrive in the mail....still i know i need a few of the mounting bolts /washers etc so would be interested in those if nothing else, and i guess if the 66 stuff turns out to be a no goer then i would still be interested. i just got so fed up waiting as i need to try and get the van through the V.I. so ican register it and get it on the road........
Thanks for asking though. your friend is welcome to try out the earlier motorto see if it fits. i know it works fine.
Best
