Yur right, my mistake. Most of theres is true 1", but you can get them in a 1.25" from them. I thought mine was 1.25", ill have to measure. I used there 26" in an A body and had to fabricate a bit to fit. You want bolt in. I understand. It is a good radiator thou keeping my 511 filled almost to the top cool. I do use a mechanical fan too.
I have really gotten no feedback on their 22" stuff that's good. Csk on here has a 26" in his Charger that does great, and just like they say, the 1" core does better than the 3 or 4 core Champion(?) he had before. I just don't get a good vibe at this point in time.
