I went to look at some bumoers for my sons 67RS.Started talking with the guy and he said he had a cowl induction air cleaner that he took off a 69 Camaro 30 years ago. It apperars to be a flat bottom one but when I flipped it over there was no vent tube? The snout looked like a Gm one-maybe it was for something else. Sorry my camera died so no pictures. May go back though. Thanks in advance for all your inut!
