Radiator for a 1975 Duster with a 225 Slant 6

I searched the forums and came up with nothing.

Three questions--I need a new radiator for my stock 1975 Duster with a 225. It doesn't seem like anyone makes one for the slant 6, and those who apparently used to, do not anymore.

Have I missed a source? Does anyone know where I can simply buy a new radiator?

Secondly, there is a decent used one for sale nearby, but it is for a 1972 Duster. Does anyone know if this will fit and work without major modifications? From what I can tell, it is 2 inches shorter.

Third, I would assume a radiator from a V-8 car would fit, the support, but does anyone know of retrofit hoses that would allow it to plumb to the waterpump and thermostat housing correctly?

Thanks everyone! Here's what I need it for:
