If you want to fly it without programming the FMC, read the ‘767 Captain’ FLIGHT MANUAL Part II – Aircraft Systems (cs767_manual2.pdf) pages 38 - 42. It describes all parts of the Autopilot for you. You can download the manuals here: http://www.captainsim.com/products/b767/manuals.html.

Basically, you would fly using Vertical Speed, Altitude Hold, Heading Select (as opposed to Heading HOLD, which could still be used) and LOC on the MCP (Autopilot) on the glareshield.

VOR 1 can be programmed (FREQ/COURSE) on the left side of the glareshield (switch it from AUTO to MAN).
VOR 2 can be programmed (FREQ/COURSE) on the right side of the glareshield (also needs to be switched from AUTO to MAN).
ILS can be programmed (FREQ/COURSE) on the AFT Pedestal (below the Transponder).
