If your truck came with the (536)HD tow package...you should have a 7 row cooler...that is 7 finned areas.....the non HD tow package for 07 was 5 finned areas and no brake controller hookup or 7 pin connector.
but I wished that have put on an even bigger cooler....
Sounds like you should be ok though....
