Marcos Maniacs

Hello;Fellows.
I am in search of the lower radiator hose for my 71 Marcos with a 
Volvo 3L.I contacted Rory in the U.K. and he told me that this part 
is not available and that I should go rummage around at the local 
auto parts house for something that might fit .I have talked to the 
local Volvo people and they told me much the same thing,so I was 
hoping that one you have hit this same wall and could give me some 
advice etc.Other wise my options are to get lucky at PartsRus,do some 
sort of a splice job,use a flex hose or some kind of combination of 
all of the above.
Any help here will be greatly appreciated!
Mark and his rotten will not last for long hose are waiting your help.
