Radiators

I dint mean "cobble" it together....rubber can be used in a manner other than cobbling.

yeah maybe if you ran steel for 3" then rubber for 4" and then back to steel a few more inch's and then back to rubber all the way to the trans I would say it was cobbled lol.

as for fittings and specialty tools.....fittings can be got pretty cheap and require the same tools you would need to hook up any other radiator anyways.

some radiators I have scene come factory with reducer fittings in the original fittings as they were used on multiple applications and you had the option to use the reducer fittings or remove them to use the original fittings.

wouldn't take much time or money and could be done with no cobbling.

I understand your looking for a hassle free direction and looking for your options.....I am just saying is that I wouldn't rule out the first option as it is definitely doable and in a reliable manner aswell.
