Can anyone tell me the length of the spacer between the alternator mounting ear and the head of the engine on a 73 or 74 440 hp in a b-body with air conditioning. The part numer is 6029591 but the parts book gives no length. I am pretty sure this fits 73-74 B-bodies and not earlier ones. Thanks in advance. Dave
