OER RADIATOR

I bought the above radiator offered for sale. I have no recourse in his feedback profile, because we did the transaction through PM. I bought this radiator as an OER bolt in replacement for my '72 Dart. It was not. I did not ask for a refund, nor did the seller offer to buy it back. In fact, I haven't heard a word from him. I am out $500. This is the 2nd time on FABO that I have been burned, doubt that I will ever buy anything again either. Leaves a pretty bad taste in your mouth.
So you bought the 4 core rad from 72Dart6pack? Why doesn’t it fit/bolt in? Kim
