Another carb identification

Car is a '73 Dodge Dart Custom and I have been told by a sales person at Napa that I have a Holley 1945, and then the owner of a speed shop local to me said it's a Holley 1920.

Which is it?

I.D. #'s
3830856
7096
1194

Then on the other side
6R
4360
B

Need to know this information as soon as possible to order a rebuild kit.

Also I am looking to go for the Napa kit, but if there are better rebuild kits out there post them please.
