1968 Dart /6 to 340 keeping original 22in A/C auto radiator

Ah Don't we all miss the good ole days when when we could walk into almost any parts store and see what could work. :(
Which is what I got to do.
This is was a '67 slant six with whatever replacement radiator someone had put in.
This is early the notebook so I *think* this may be similar assuming the radiator in the car had similar inlet and outlet to the original.
Top Hose: Dayco 81181 / M08 1 1/2" ID, 19 7/8" Length.
Bottom hose: Dayco Flex? hose 81251 / M33 1 3/4" ID to 1 1/2" ID, 16 1/2" Length.
may need to shorten pump end by 1/2" and the radiator end by 3/8"

I hate corrigated hoses too, so if that was a flex hose probably replaced that when I found something better. I'll see if I can find that info.

edit: no luck.
