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!!!

Unless you want to be "cool" with a MCH-208 Pulley.....the secret of changing Alternators is to switch pulleys from existing Alternator to New Alternator when installing Alternator. That way you are sure the EXISTING Serpentine Belt will fit with proper Belt Tensioner Operation.
A Very Easy Job changing these Alternator Pulleys after installation of Alternator using my modified 15/16 inch Box Wrench and 5/16 inch Allen Wrench. You can change these Pulleys AFTER Installation of the Serpentine Belt. Matter of fact........Install the Serpentine Belt as you change Pulleys placing the new alternator pulley inside the Serpentine Belt that has been installed on all the other pulleys. With the Serpentine Belt Tensioner Compressed, lift that New Alternator Pulley inside the Serpentine Belt up on to the Alternator Input Shaft and install the Alternator Pulley Washer and Nut. Tighten the Alternator Pulley Nut and you are DONE.....Release the Serpentine Belt Tensioner.
