well working radiator for 1966 Cuda needed ASAP! For automatic 225 slant six

Instead of using a 19 in slant radiator, you could do what I'm doing - I took an early A 22 inch V8 radiator, had it recored to a 3 core (optional in this case), and had the radiator guy remove the old V8 hose nipples and add the slant ones to the radiator where they would have been placed if a slant 22 inch radiator had been offered for the early A. Don't care to do that, then the interchange is a 63-66 slant radiator. You might be able to swap a 67-later by redrilling the mounting holes in the side panels and/or core support.

I will look and see if I have a good gas sending unit.
