Interior code question /66 - trying to pick the right leather for '72 seats

[Polaris]

The COA for my '72 S Targa lists Black Leather/66

What does the 66 mean?

I'm trying to choose the right leather and so far I've not been able to find a previous owner of the car that recalls what combo or leather or material was on the original seats (perf, cord, etc.)

I'm planning to send the Sports Seats to Tony @Autoban based on the great reviews I've read. Likely I'll just go with Black Leather on all surfaces unless swayed in a different direction.

Any guidance appreciated!

Karim - you are AWESOME! Thank you so much.

Please note that the 66 code means that it's a full leather interior, not only the seats.
Elevenparts in Switzerland has a nice pair of original leather sport seats

Andrea is right.
66 would be full leather interior ("Genuine Leather Trim"), including interior trim, seats/bolsters and insert.
Leather seats, Leather Basketweave inserts and Leatherette/Vinyl interior trim would be 21. (Edited: 16 !)

Below the 1971 version, trim codes are still valid for 72/73 (2.4l seat materiels changed, however)

Here's the 72/73 one.
Karim, I think that the leather seats with leatherette interior would be 16. I have this on my 73S.

yes 16, sorry Andrea. I edited my post.
