Yeah thats a 73.5" belt. I am running a 74" w/ an aux idler w/ a 90mm pulley & have had no belt slip issues. I had to go w/ the 74" in a pinch & it has been fine. Just saying.

Thats the part number for a 73.5" belt, which would be really tight. Do you have an aux idler pulley also or did you just change the blower pulley?

You might want to think about picking up the aux idler pulley to prevent belt slip. That smaller pulley will have much less belt contact, and the idler will help wrap the belt around the pulley better.

oh gotcha never read that before, got any links? its basically just a bigger idler pulley to make more area on the belt contact the blower pulley?

It's a pulley and bracket that mount next to the blower pulley. Here's a link to where you can purchase one.
