Steve, Sent you a pm, I think the edelbrock performer is the only one that matches up with the gs air cleaner.
Not trying to state the obvious but I think this is a dualplane the description says a "Split Single Plane", kind of a strangeway to say Dual plane I think anyway.
It is indeed a single plane (see photo), I used to run one. The "split" refers to the center divider in the plenum separating the left bank from right. Devon
