Carburetor Confusion

[originalowner70superbee]

So.....I have been doing some research trying to figure out what the correct carburetor is for my 1970 Super Bee 383HP w/A/C. I have three in total....one on the car ans two that my dad had in the trunk of the car in a box. The list number are as follows:

List - 4369-1 (3639)
List - 4749-3 (3425)
List - 4749-3 (3437)

I just realized that two of them are the same but I don't know what the four numbers by themselves mean

the 4749-3 pops up on several sites as the original carb,but i am still not certain.normally the #'s in () are just production reference.

Ok thanks....I wasn't sure which one was the correct one. I didn't know if those other # were a date code or some special reference.

The 4369-1 is the one I say is correct. It is for AC. The last 4 number sequence is the date code 363 (day) 9 ( year 1969 )
