I think it will fit your GMC pretty good. not so well on a Chevy due to the different rear suspensions.

then again I would rather go with a local custom bent set. with that you have a say in how it is run. I wouldn't be too concerned with the bends since you are going 2 1/2" unless you have a real healthy 454 or larger and will spend a lot of time at high RPMs.
