Chapparal st80 shift adjustment question

I have a good running early 1970's Chapparal st80 that I need to adjust the (inner) shift linkage for.....I understand that a Hodaka engine (also Fuji) is very close, but there are subtle differences that have got me baffled....any experts (or novices) out there that can help? :shrug:
Figured it out....the previous owner (backyard mechanic) installed some home-made
junker parts....had me baffled for a minute......I installed the correct parts salvaged from an Ace 90 (Hodaka) and it shifts fine....I would close this thread, but can't figure it out!:eek:ut:
