I realize this thread is pretty ancient now, but just in case any newbies, like me, come wondering in, Bobchevy gave the following invaluable advise:
You can get a owners or service manual from Helen Davia Secretarial Ser.
PO BOX 484
Sidney Oh.45365
Ph#937-492-8885
runs about $35.00
I called and was able to get a users manual for my '75 Argosy, now all I need is a service guide, any one offering?
Cheers,
Andrew
