I think i may have a spare paper one down south - i can remeber seeing a round paper gasket thing when i got my stock 2t carby reco'd 2 yrs ago ..
Im pretty sure its in a drawer at my folks place - if you want ill get them to peek for you next time i ring them ..
BTW - justin - are you restoring yours to stock ( concourse ) condition ??
If so - id like to hear more about it - Also have two stock aircleaners as well for 2t - one that has the indictuion horn thing that goes across the tappet cover to the passender side - the other is one that runs toward the front headlights - Which ones the true original one - just out of curiousity
