30 31 radiator

This looks like a 30-31 radiator, but is it?

What does the back side look like?

It appears to be a 30 - 31 radiator, but it is not an original based on the upper tank.

160B, This is what I am thinking...has anyone ever seen an OEM 30-31 radiator with the vertical outdentations stopping before they reach the top like that? Was it a 1970's pop off of some kind?

On a original radiator the side frame is not flat, it has a curved indentation. If the side frame is flat it is a reproduction. I do not have a good photo of the side frames. Here are some more photos of an original tank and the dimpled fins.
