The only dizzle radiator I've done was the CUCV, but lessee... Besides the actual water plumbing (i.e. radiator hoses), it should have two connections on one side for the tranny cooler. It may also have two more on the opposite side for the engine oil cooler.
The tranny cooler is just your basic pipe thread stuff, uses the same hardline you'd use for brake or fuel line, flared fittings.
I'm thinking the extra hardware is for the oil cooler hookup, uses fittings like the new-style power steering stuff?
