Hi Bob
Thanks for mentioning this approach to coming up with a correct belt length. The $10 a foot cost isn't to bad if you figure in how many trips to the parts source you can save. The adjustable belt is a great little invention not a new one been around for long time, here is a link to the installation instructions for one type

http://www.fennerdrives.com/ here is the link to their Catalog
http://www.fennerdrives.com/catalogs/hpcvbelt.pdf picked this company as they had better pictures of the belt, no other reason. In looking I did find that Harbor Freight has it listed
http://www.harborfreight.com/vibrati...elt-43771.html for $25 for 5 feet but it is on back order.
Given how hard it is to install a fan belt on Chevy CMPs because of limited access and the close spacing of the fan to the radiator, having a length of this in your "end of the world" spare parts box in the truck might not be a bad idea.
Oh and thanks for giving me the topic for this months Tech Tips in our MV Club Newsletter.
