A31pkg & sixgunrunner68, thank you. Confirms the path I been trying to go.
It is strange how it seems difficult to find online info on the radiator subject.
I have the 383.
The opening is exactly 22inches, the car currently has a radiator that measures 26inches and the core overlaps the opening by 4 inches and the drivers side bolts are only things holding radiator in.
There are 4 ancher nuts around the perimeter of the 22inch opening.
Therefore with your replies and what I've said, do you agree that I need the 22inch?
Where the h_ _ _ am I going to get one of those?
Yearone has them but not original type right?
