As usual I relied on my brain instead of my O/M. I ordered a set of Silverstars 9006 and 9005 due to the fact that all the gm's use these bulbs. When I got my bulbs and went to install the highbeams I looked at the OEM bulb and it was a 9011, rated at 65 watts. The silver 9005 is rated at 60 watts. Any of you pro's want to help me out. I went ahead and installed the 9005's and will see how the do. Any advice as always would be greatly appreciated and a belated Happy holidays to everyone.
