LY6 - Vacuum port??? I just picked up a 2008 LY6 6.0 from a 2500 Chevy pickup with hydroboost brakes. It does not have the vacuum port on the back of the manifold that I have seen in other posts. Am I missing something obvious or will I need to make a mod of some sort to get vacuum for the power brakes on my 79 Toyota LandCruiser?
