OK here's what I could find; RPO code ZW4 73-80= 2.85, 1.68, 1.00:1. ZW4 was changed to M-15 for 77-87. M-15 81-87= 2.85, 1.68, 1.00:1 w/350. 3.11, 1.84, 1.00:1 w/305. 3.50, 1.89, 1.00:1 w/250. Also the Saginaw 3-Spd 2.54, 1.88, 1.00:1. I do not know how you would tell the differences but this is what I could find out. Good Luck...Jon
