I just wanted to put my experience with this out there, I added the metco lower and the billetflows this past week. (I have the lowest pulley mounted in the upper whole on the metco bracket) and I had already had the steada 2.8 pulley already, but when looking at the belt guide provided to us by stangshiftergasket that combo is not listed, they list 3-90mm and 1-100mm pulleys, but that's not what I have. So I first tried the Napa Gates Micro-V 080810, its 81 5/8" long suggested for the 2.93 pulley. It went on ok but the tensioner only had 1/4 of its travel left, and I was worried that after the belt wore in it would slip. So I called Napa and asked for the next smallest size which is the Gates Micro-V 080806 which is 81 1/8". i installed the belt and it was a tight fit, but the tensioner now has 7/8 of its travel and it doesn't seem to have any more "between pulley" tension than the other one. Hope this helps someone out down the road.
