dutch those little parts look like they go on the shifter paw, there should be 2 small springs that hold them in place
when you took case cover off did you pull out shifter rod, is so then the paw might have come apart, but i thought there was something else that held it in place, not sure on the 85-86 tho
thats why they looked familiar!! Those are a B**CH to get back in the right place on a trx450r.... and you're right because i didnt pull them out of my 87 when i tore it down but again, thats an 87 not the 85/86
