I am having some difficulty in finding component dimensions to determine whether they will fit in my cowl space.  I have been considering two possible plumbing methods and would appreciate comments.

One:
Along the lines of Ed Anderson's. As I understand it, he welded an AN-16 bung to the radiator (evaporator cores) and then used AN-16 hose to connect.  I believe that his hookup is in series, so the flow is the same through both radiators. Ed -- how much space is needed from the welding surface of the evap core for the curved end of the hose-- before it hits a cowling? Also, are the fittings really on the order of $175/end?

Two:
Tracy used smaller heater hoses in a parallel hookup. Water flow through the radiators may or may-not be identical, harder to insure, since hose length will be different.  Tracy, Does the aluminum tubing out of the radiator bend before being attached to your hoses, and what size is it. I am having trouble finding short radius bends to fit that could be welded into place.

Looking for all input
