radiators for the /6 A body...

I think it will bolt up, but as mentioned the tube locations varied. I recall all slants have a 1.5"D lower tube on passenger side with a unique bend upward. The upper tube is 1.5"D (all Mopars I think), but probably varied depending on where the AC compressor was and perhaps also between AC and non-AC cars. Shroud mounting holes on the brackets might have varied too.
