LR60 Active Member Apr 15, 2021 #1 A YIO-390-A3B6 is what I purchased from Vans according to all their paperwork and invoices.. A YIO-390-EXP60 is what Lycoming sent me. Is this just a case of Vans forms and invoicing not keeping up with Lycomings model number changes? Or is there other differences. Thanks
