Classic/Antique Car Repair: 1960 AMC Rambler Carburetor, carter carburetors, carter carburetor

Question
I am trying to find out how to get my hands on a rebuild kit for my Rambler's carburetor, 1960 I6 engine.  It is a Holley one barrel but I can not find any markings on it (not even near the fuel inlet) to identify it.  It is a one barrel Holley with the rectangular forward facing float chamber.  All the web sites I've visited suggest that in 1960 the Rambler had a Carter carburetor, but this one does not.  Thanks in adavce for any help!

Answer
I apologize for being slow to answer - the allexperts system is having some kind of a problem - I got no questions for a few days, now there are a bunch of them stacked up in my in-box!

The 1960 Rambler used the Holley R-1598-2A on a few cars, although 99% of them had Carter carburetors.  The kit for the Holley is 85R-709.
