tough carter afb identification

This AFB might be a early Pontiac or Buick/corvette carb.Carter back in the day only gave serial numbers to some companys,mopar being one of them.I have a few of these carbs and they have no casting numbers or ID numbers,and can only go by the throttle brackets and bore and venturi size to ID the cfm and the application.Is the fuel inlet on the drivers side or the passenger side? Does it have the 2 mixture screws and a third air screw that is larger than the two mixture screws.Does it have a round ball pivot for the throttle linkage?If you can post a picture of the carb,I will id it and tell you thecarb kit you need or send the pictures to me at: [email protected] mrmopartech
