Rochester Guru's Need some 2bl help

I have this three duce set up on my truck, but I'm not sure what year car the Rochester 2BBls came off of.
Can someone identify this bad boy for me so I can order a rebuild kit. (or another carb)
The two outside carbs have no idle circuit, but match otherwise.

Thanks for all your help.

That looks like the early type used in '57 , same as on my coupe. I'm pretty sure that the rebuild kits cover all 2g and 2gc Rochesters. The later ones had the fuel inlet on the side of the bowl. The guy at the parts counter is going to ask you for a part number or a serial number or something and you are going to have to tell him that they are Rochester 2g and 2gc carbs and those are the only numbers on them and if he knew what he was doing he could find the right rebuild kit with just that information. Good luck!

 

Only 57, or 57 through ???
Appreciate all the help I can get.

Walker carb kit pn 15289C should cover you. The kits have all the various gaskets for the different 2 GC's.

 

carb may be 57 pontiac or caddy center not 348 chevy i get my carb kits from autozone part num 96-111D or 15289C these kits have enuf gaskets for most small based roch 2GC carbs

Look like 57 chevy truck carbs,or as said pontiac had them also,the vent is what makes them distinctive used on early man-a -fre set ups.
