I just put one in a 62 Corvette we're doing a restoration on. It's nice, but attention to detail could have been better. They have two nubs on the bottom that slide into two grommets in the bottom of the radiator support. They were welded on in the wrong places. They were close enough that I was able to lube them up with PBlaster and force them in since the grommets are rubber. Also, the driver's side of the bottom tank was made in such a way that we had to cut the driver's side end of the bottom of the radiator support to make it fit, and the bottom tank was so wide front to back, that it hit the front ends of the frame rails and kept the two nubs on the bottom tank so far away from the grommets there was no way they would go in until we also trimmed the ends of the frame rails up. Of course, this car has gotten a Mustang II coil over front suspension along with a lot of other non original parts, so it's not like it's a correct restoration. But still, that's a lot of modding to do for something that costs a lot of money. It should have fit right. Lastly, the bottom frame of the core also had a bend in it from shipping. It was not bad and will not effect performance, but still, it's there. The owner told us to go ahead with it, so we did. I don't mean to be bashing the product, just giving an honest mini review of what we found. It's a nice radiator and I am sure the little stock 327 will never over heat, I just wish the fit and finish had been better. As for the bend in the bottom of the core frame, I'm not sure how it happened. I would assume in shipping, as surely they are inspected before they are shipped. Obviously though, they are not quality controlled very well, or the mounting nubs would have been in the right places.
