Cometic O-Ring identification

[Heatnbeat]

The Cometic gasket kit for my 90 Ultra has 3 #R020B Buna O-Rings and I don't know where they go. It might become apparent later in the assembly or they might be extra but I don't want to get too far and find out that I left them out. Any idea where they go? I thought I was missing 1 but the list says 3 supplied. 3 seems like an odd number on a twin.

THANKS!

that's not a H-D part number you'll have to ask Cometic .If you measure them with some calipers we can make educated guesses

Will do!
