Small Con Rod bearing size or supply Yam/mariner 689?

Hey all,

Me again! On the quest to waste more money, I'm just having the crank shaft rebuilt, I've managed to source new bearings (not OEM) so saved a heck of a lot but I need to source the small end needle bearings. I'm pretty sure they are 18x22x21.8 and I think the part no is 93310218A6. Can anyone confirm please or even supply them?

Heres links to both versions
