Grumman Olson Routestar 1993

[IndigoMarsh]

A question for Grumman owners or aficionados or anyone who otherwise might be able to help me. Is there a place I can buy a manual like a Chiltons Service manual or something of the likes?

Also, how does one tell if they have an MT45 or MT55? I'm going to guess by body/box length? Mine is 14'

Thanks
