59 AB intake ID (stock)
 

I know the blocks these came off of based on Van Pelts site. What I have are a 41-42 (right/Blue) and a 46-48 (Left/orange). Are these intakes matching that? The blue has fittings on the left side that the orange/Dirt one does not. The Orange/dirt one has a groove cut between the carb ports.

Thanks

the older one may have a vacuum port for the early distributor.

The blue manifold has provision for two vacuum lines, the forward line goes to the front center mounted distributor, while the rear line supplies vacuum for the windshield wiper. The orange manifold is for later engines having front side mounted distributors, for which vacuum is supplied directly from the carburetor base.
