Suggest you look elsewhere for your new radiator.
Griffin has now been entered on my "no fly list".
Here's my sad tale of what I got for $400.
This pos is way out of flat. At least 1/2" of twist. So bad it can't be mounted on the core support.
Called them up.
First reply: "Send it to Summit and they'll give you a new one".
2nd: "You modified it with brackets, no warranty". That brought more about the box, the shipping caused it, bs.
3rd: "Since we won't warranty it, it makes no difference what the cause is. You can try to straighten it or buy another one".
How would you suggest doing that? A leading question!
4th: "You can lay it on a flat surface and bend it".
Sounds like this isn't your first complaint.... Crickets.
Watch the Chevy boards... you are going to be "famous"��
I've been made aware that this problem is widespread.
This is the last of their junk that we'll buy, that's for sure.
Should have shelled out the real bucks....
