options for running vintage A/C and heater hoses with smooth firewall.

[portworks]

I know there's been quite a few threads about this before but I'm looking for a clean alternative to go possibly straight through the side of the cab above the fresh air vent and possibly into the passenger fender area. I would like it to be hidden as much as possible. Looking for experience from someone , with pics if possible. 1968 factory a/c cab.Smooth firewall.Newest vintage air kit.
