Wanted: Carter 4933 Carburetor (Rebuildable or Working)

Thanks, but I didn't really see where they explain if my 4speed w/out A/C requires the soloniod?

From that link on the (S) at the end

I am a little confused, they put the (S) at the end to denote assembly? Does that mean, all carbs put on assembly line cars got the (S), where as an over the counter purchase of the same carb did not get the (S)?
Thanks for your help, I'm pretty green to this stuff :)
Difference betweer Carter carb 2366S and 2366SA. There are multiple parts on the carter carb itself so the part number with the s is the complete assembly rather than just 1 part.
