For what it's worth...
I went up to the local independent auto parts store and asked to browse the radiator hose catalog. I had some rough measurements of the distances of the openings on bottom of the radiator inlet and outlet tubes to the ends of the tubes running though the spine of my RCR 40. My mission was to find an off the shelf heater hose(s) that would easily fit a 40. I came up with a Goodyear hose (Part #60710 @ $13.99 U.S.) that will work for both sides with or without a heater core. It will require splicing in a tube (aluminum/steel with bungs) for the heater hoses if you decide to go with the heater. Should save you buying four hoses if you like the look.
I don't know what other cars they will fit. However if you have a 1.5" OD tubes for both the radiator and center/spine tubes I imagine you can get them to fit. The guy in the store said I could return them if they did not work out (uncut of course! :laugh
.
I have attached pics from my car to show the fit. The close up is upside down so you can see the hose number. I have set them in my car just for this post.
