For 1991 VP570 eng. DP-A drive...Is there a factory manual(not SELOC) for my VP. I see a guy on ebay from Fla. that claims he has a CD .pdf version but I'm not liking the feedback on him. I've heard things like VP never a made a public factory manual and downloads of them are not the real thing? I dont like seloc because it covers such a broad range of models through so many years. Is there a model or year specific manual out there? I see Mar.Eng.com has one for my VP but is it a actual VP manual or seloc?
