Apparently it is for a V-8.
I have a V-8 1966 barracuda and the lower tube was on the wrong side for it.
The lower was on the passenger side on the radiator.
That is why I am getting rid of it.
I have no need for it.
If interested, I will take $150 plus shipping just to get it out of my shop.
Or I will trade it for a radiator that fits a 1965 Slant 6 barracuda with auto transmission lines.
