'68 vs '69 Factory Service Manuals

[Jerry Phillips <jnpvegas@xxxxxxxxxxxxx>]

     When I had my '69 AMX I also had a '69 factory service manual.  It covered the AMX and included the 390 engine.  The '68 factory service manuals I have seen include the Javelin, but only up to the 343.

     Since the AMX was a mid-year introduction, was the service manual for '68 ever updated to include the AMX along with the 390?   Was a supplement addressing them ever produced?  What do owners, particularly with early production '68 AMXs use?

Thanks in advance,
