72 Big Block Heater Hose Question

[SavageC20]

I am replacing the heater hoses on my c20 and I am wondering if there is a 5/8"molded heater hose available that will somewhat fit the area marked in yellow.

If not does anyone have pictures of their heater hose setup on a factory big block truck?

I am also having a hard time figuring out how to route the 3/4" hose that runs from the radiator to the core on the firewall. It does not want to bend sharply enough to clear the A/C compressor pulley.
