6-rib belt size

I am finally finishing my 4-rib to 6-rib conversion and also went with a smaller nose pulley. My setup will now be a MP 62 hotside with a 150mm crank pulley and a 62mm nose pulley. Track Dog use to have a great belt size chart on their website that made it super easy to figure out the best belt. I plan to do the string method, but wondered if anyone happened to know the exact Gates belt # I need for this setup?

I added the -525 & -529 belts which weren't in the original chart.
