Got my belt in today. It's a bit shorter than I need which stinks, however it doesn't matter anyway. The Kpower adjustable pulley I bought is useless for anything above a 6 rib belt. The space between the walls of the pulley are 2.6 or so mm too narrow. I've sent pics to Kpower so we will see what they have to say. Luckily this doesn't stop me from moving forward but does suck to have to deal with.
The alternator pulley for reference.
