185 Dorsal fin gasket source

[Tom3holer]

Hi,
I have a 185F and the black gasket that extends from the rudder to the L/E of the fin and the fuselage need replacing.
Bought some from Aircraft Spruce of the correct dimension but it was very thin; not like the one on there now.
Where can I source the correct gasket material?

Thank you,

Tom

My early C180 IPC calls out S-202RB.
I bought some from Univair a couple years ago, $.63 / foot.
I think I needed 14 feet or so, I bought 20.

Looks like its about 3/8" deep....
