Looking for an original smog pump pulley for a 428 with AC. These pulleys are different than the regular smog pumps since they share the AC belt and need a wider groove for that. Engineering number is a C90E-9C480-A and used on 1969 and 1970 Cobra Jets. If you have one to sell let me know. Email, text or phone is the best to reach me.
