All of the belt Sizes in the Stickies are for V2's with all the different size pullies but I need the correct size for the V1 blower with 3.125 pulley and where to buy it ??

You're gonna want a 695 length belt (last 3 numbers of the belt should have 695 in them) for anything from 3.6" to 3" on the V1 blower plate. I have the 3.25" pulley and I am using a 695 length Gatorback belt for it which I bought from Autozone.
