Depends on the look you want for your truck. The 06 GM large SUVs have an integrated shoulder harness that gives some extra support for your passengers if you're looking for it but will lose that period correct look of the K5.

I was lucky enough to score a set of fronts and a rear out of a 69 in great condition for relatively cheap that I rigged to fit in my 72. In the future I'll look to swap out for the tahoe seats when the clan grows.
