[C10 - C90 Bill]

Bob,

Right, the '72 has a different part number. Someone told me the '67 to '70's are no problem and '73 and up are no problem, but the ones for a '71 and '72 are hard to find.

I even checked on some NOS ones, but no luck there either.

I finally found a vendor that verified the C-20 one will fit the C-30, or at least the one he has will, but it will be out of foreign made rubber.

When I checked with another local parts store, he mentioned what you also have stated. He can send out to have some made up. I might go that route as the nice part about that is he said it will be made with US rubber.
