build sheet question

[greasyspider]

I was just checking my build sheet for the radiator numbers and noticed that under "carb" it says 33.  Is this the last 2 of the part number like it is with the radiator? Because I could have sworn my carb should be a 4966.

Yes. 
3512833 is the Mopar part number.  Carter 4968S.
4966 is Plymouth, Dodge, Chrysler (C body) 440 automatic.
I'm guessing you have an automatic as well.  so 4968 is the correct one but I have no doubt that 4966 will work fine.

68, yes. Thats what I meant.  The old one I had was a 66.
