64 stepside radiator upgrade question?

[McCoyAZ]

I own a 64 stepper that isn't where I am located.

I have an opportunity to buy a 4 cre aluminum radiator w/ fans but I don't know if it will fit the truck.

Will this fit?

4 core aluminum radiator with dual electric fans and external trans cooler, driver side top passenger side bottom(chevy style)
measures from outside of tank to tank 32" X 19" tall, inside the tanks measures 25"

We swapped out the engine to a 283 with a 2 speed auto trans.

Thanks in advance for the help.
