carter 1bbl carbs

What's the goal, BB? There are several disjoint interchangeability groups in the year range you mention. You're trying to build up shelf stock of rebuilts for customer cars...? You're trying for one carburetor for one car...? More detailed request, please.

Carter BBS carbs were used from '60-'71 on passenger cars, '61-'74 on trucks and vans with slant-6s.
