HIall... Moatly for Hugh, here are the Goodyear belt numbers for the 58 392. Generator: 15406. Generator on a/c cars: 15701 - set of 2. Generator with 40A Gen: 15396. Generator and idler ( mopar w/ air ) 15550. Power Steering : ( with or without air ) 15456- set of 2. A/C and idler : 13621 - set of 2. That is from a July of 1998 Goodyear catalog, any competent parts guy can change those numbers to their own brand. You may find that these numbers are the same as some other brands too.
