I am in need of a parking brake switch for a 70-71 Camaro that grounds to make circuit with the warning light on the dash. Looked and called NPD, Camaro Central, OER, Rick's, Classic Headquarters, Classic Industries, AC Delco, M&H, InLine Tube, SS396, Rock auto, eBay, Amazon. Coming up crickets for this two year only part. Anyone have one for sale? Original GM part no was 3983909. I will take anything that fits. Saw someone posted this excellent pic in the past.
