Will the pacesetter LT headers I took off my 2000 Formy fit my 2007 5.3?

This could save me some money, lol

i would do some serious checking, the tube length might interfere with your truck frame...etc

they will require some bending to clear the firewall/ frame, but it has been done before, they will bolt right up otherwise

I'm curious about this as well, because I have a brand new set of Stainless headers for my 00 Z28 that I don't need since I'm selling the car. How much bending(and trouble) are we looking at? Who all has done this and made it work? BTW my truck is the 04 6.0 in the sig, don't know if it is much different from the 07 or not.

sell your other headers and go buy some new pacesetters coated for $400.00 it's going to takemore time to bend and try to get them to fit then it's worth in my opinion.
