Here's how mine are laid out on a 68 Deville 472 w/ AC:
Starting at the 12:00 position looking down on the carb from above:
12:00 to transmission (hard metal tube coming up from beneath firewall
4:00 to vacuum switch, driver's side of distributor
6:00 to PCV valve (large line)
7:00 this one's a pain: line coming from carb 7:00 position and line coming from pull-off diaphragm come together in a T. Third line comes from T over to vacuum switch in to driver's side of distributor.
10:00 yellow stripe coming in from hvac lines to idle speedup diaphragm.
Hope these help - I know they could be a little more descriptive but I'm going from memory and can't scan you a pic of the manual right now.
