Thanks for the pulley tip Cliff. I also do have a spare serpentine belt. But hopefully won't have to worry about that soon, as one of the PO's had that replaced back in 2010 along with getting the belt tensioner rebuilt at that time. And its only been 12,000 miles or so that have been accumulated since then. I was lucky to get about 10 pages of service records from the Chevy dealer that did all of the work on the Z.
But you never know, always better to be prepared to an extent, rather than not!!!
