Are there also different sizes? I will decode mine but is there more than these sites show. I know mine is the original on my 68 327 with air 400 turbo.

Thanks
Dave

I have book full of numbers on the carbs. Let me know if you need one deciphered. THe ones listed are:
7041206 '71 20&30
7041209 '71 10
7042206 '72 20&30 auto
7042207 '72 20&30 manual
7042218 '72 10 auto
7042219 '72 10 manual
These numbers are on the side of the carb and they should help.
