where do I get one of these

This one looks like bonnie and clyde got hold of it. I put water in it and it looks like I am gonna put it in momma's flower bed for a sprinkler. The number on it is 3673015. I am gonna put it in the right wanted ad here but do es anyone know of a good radiator shop that builds them. this is a 2 row but I would like to go 3 row. There is enough room for it. core size is 18Hx 26W. I took it to my radiator guy who done all my work when I was in the trucking business and I think he was trying to rape me. so I thought I would come to you guys before I became submissive to him LOL. i would like to use my tanks because it has the pentastar logo on it and all the hookups. It is for a 73 Dart Sport. I hope it is ok to put this here also.thanks,Bill
