Mustang 770-2 articulating loader

[Budkris]

Where can I find a parts manual for a Mustang 770-2 articulating loader made in 1976 at owatonna. Mine will not move forward or reverse.

Don't know what the difference is between the 770 and 770-2 is but Google brings up lots of parts and operators manuals for "Mustang OMC 770 articulating wheel loader". They seem to run about $35-$40.
