Woods RM59-1 question

[DR1]

I have the part number 31700, and have crossed it for NAPA, and it comes back as B180 which I am assuming is a 180" belt. I get so many mixed belt lengths that I wanted to see if anyone can tell me what length belt they have actually put on their mower?
Thanks.

If you have the orginal belt mark it then lay it on the floor & measure the overall length between marks.
Wish I could help but mine is a RM59-3
