Correct heater hose routing and ground strap placement

Hey guys! I've got a 65 cuda 273 2 barrel and am looking for the correct heater hose routing. Some I see going over to the right inner fender and fastening to that before going to the heater core. My inner fender has no holes in that mounting area. Others take a more direct route and just use a metal strap(s)? to bind the two hoses together. What's factory correct?

Also, the ground strap between the engine and firewall, where exactly are the two fastening points?

Long live the FISH:cheers:
