Hood Bumpers? If that is what you are needing try the closest wrecking yard and pull them from any early model car you see, Ford and Mopar seemed to use similar--I must have pulled 20-25 from various models for my car, cost me $5. I used a pair from a early 70's Connie, soaked the rubber bumpers in motor
