New Upper Rad Hose

Has any one got an idea of what P/N or mod yr of vehicle I need to get one from, for my new aluminun radiator, ??, the upper out let is on the pass side, going to an LD-340 Eddy Manifold, on a new 340. I'ts a new "Northern" aluminun rad.

The stock rad had the out let on the driver side, and I don't think I'll be able to just walk in a parts store an get one as easy as the stock one.

I prefer a smooth molded rubber hose and not the convoluted type, for better flow.

Just wondering what you guys that have put in new aluminun rads, have used on the upper hose. The lower hose is on the same side as the stock rad.

Thanks, Dave C.
