Just send the original to Glen Ray and have them up grade it. Stock looks better than a cheap looking non fitting aftermarket radiator any day. That is if you still have a factory rad.
and if you don't have the stock unit he is repopping some and i believe he has a stash of used as well. He's not cheap, but QUALITY never is. I will also add he would've saved me about 18K or so on chasing a BB heating issue that magically vaporized with his core even though the radiator had a NEW core in it VERY LONG Story.
