My 58 did not come with a heater (go figure as it spent its life on a ranch in central Texas) but I have acquired all the parts. Now for hooking it up. I've found this pic on Walcks site showing the fluid control valve, but I'm not sure where the hose routs from there to the heater, as well as where the two cables go thru the firewall. I know there is a port on the passenger side of the head that connects to presumably the heater core port closest to the firewall. So any pics of what is thought to be original would be appreciated.
