From my understanding, talking with them, they should be the same price( if we can get a truck up to them).. Hell even the 6.2 headers might fit. I know the exhaust ports are the same, for the 5.3-6.2's, but I am not sure how the rest of the body under side is, motor placement( I think it might all be the same but not 100%).. Anybody want to buy a set for a 6.2 truck and give it a shot

If it turns out a 6.2 set of headers fit nnbs 2wd then they might fit the pre 07 2wds also..
