Started yesterday got the radiator in mint condition from a member her and got the idea from garth285 who was probably the first person to ever do this and told me how to do everything. i took some side by side pictures of the size difference. the 07 is wider and mounts the over flow tank on the opposite side. I ordered an aftermarket one from motion pro so that i can mount the overflow tank on the same side. As soon as i get the over flow tank ill give some feedback on how much cooler it runs.
