The filler necks are soldered in. If you heat the connection, wait for the solder soften, you can turn the neck any direction you want. New filler hose isn't very flexible so take that into consideration.

The part numbers are GM14C for the 31 gallon and GM25C for the 40 gallon

There's a decent picture of installation into a '69 truck in the link you posted. I elected to mount the tank the other direction and turn the filler neck. My fuel lines run up the passenger frame rail.
