A question...

[Xplantdad]

My bro's Camaro is supposed to have the smog set up on it. Over the years, he's collected morst of the parts needed to put it back on. He's missing the biggest part, the smog pump. Since I know nothing about this I'd like to pose the question...do they make a reproduction 1967 big block Camaro smog pump? Are the reproduction pumps functional...or just the housing? Or, should he look for a real one? OPinions...comments are always welcome.

Thanks.
