Yes 211 would be correct for your application - have 212 (for 4 speed) and even 211T for M code with automatic (very early GT350)
There were real paper stickers with a clear layer over them but they fared poorly over time and in most cases you normally only find the pattern left from the adhesive if your lucky. To that end
From a 12K mile 69 San Jose M code, automatic special order paint car I took pictures of about 25 years ago (sorry for the felt tip markers - way before digit
Hope it helps
