I took a picture of my factory 26" SB radiator down to OReilly's and flipped through there book unil I found what I wanted.
I'm sorry I didn't write down the application, but it was 4 row "Heat Buster" radiator for a different mopar application. It was ~1" taller then factory, and I had to drill one new hole in the bracket, but otherwise it looked totally stock. I just pushed it a little farther down so the top was close to the factory location and drilled the holes.
I think it was just under $200. I never had any problems with it, which is saying a lot living here on the face of the sun.....Austin, Tx.
