I have a cowl plenum air cleaner AC part no. 6422373. Does anyone know application for this air cleaner. I posted with pics. under the Lounge section ( buys of the week) probably should have posted here. Any help would be appreciated. Thanks Grady

I dont know what that one is for but it sure looks cool. I remember seeing one on a 67 or 68 z.

Looks like 1968 Z28 with indent for A.I.R. pump

I believe the indent is for the removal of the fill cap for a bigblock car
