I am thinking about getting a new replacement Sport Steering wheel from the Parts Place (unless you have a better recommendation) and I need the spring and contact thing that slides down inside the steering column and makes contact to the steering wheel/horn button for the horn circuit. Hopefully what I said makes sense. I am not sure if I understand what I said! It's a 1971 Skylark with an automatic column shift tilt column.
You are correct parts place should have it Three piece set pin, spring and retainer I believe they may sell a whole lkit wheel, Buick horn center cap, hub, screw kit, and horn contact. Contact ToddGS he’s a dealer for the parts place and has a better price.
