What I did find is the pulley needs to be 76mm in diameter and I think the width is around 32mm. This weekend I will take some measurements of mine and then get the PN from the Gates catalog. Hopefully I can see the PN and remove all doubt.........

As an FYI: the SC belt is a Gates K08022 or Magnuson M-79-08-02-020.

Vortech 2.95 SC pulley is PN 2A038-295
Idler pulley needed is (maybe) Gates 36225. I need to verify this!
