It may be this the one you´re looking for:

It is a 3x2 waterheated intake and it´s suitable to use a carb called here DFV. If the "2G" you´re talking about is the Rochester that came on Chevys like Chevelle, Camaro is the same bolt pattern.
I know because I once used a 2G (from a 307 Chevelle) in my Opala on the top of a DFV stock intake. So as the bolt pattern won´t be a problem you can buy it without any worries. The main concern is about the shipping costs.
