Radiator ID Help

A three row core will fit between the tanks. That's what I did to mine.
I think a four row would fit in it. I know it would fit the top tank, as there's still room at the back, but I believe it'd have to have a different bottom tank.

I'm going to take it to a friend who owns a radiator shop in Macon and get it checked out. If it's as good as it looks, I might just swap it in Vixen. She has a newer aluminum radiator, but I prefer the stock look and I think this one will probably cool just as good.
