Hi Thanks for the reply
I assume Napa is a parts supplier in the USA , on the other side of the pond where i am
(United Kingdom) we do not have this parts supplier ,do you know what length they are so I can match it up .

In America we usually don't have fans on our Mastercrafts.
Seriously though, based on that napa part number it's probably a 48" (~122 cm) 6 groove serpentine belt. You should be able to find that at any auto parts supplier. There is some variation between what different manufacturers call 48". Sometimes they vary up to 1/4-1/2" in my experience. So, if you grab on 48" and it's a hair too tight or loose just try another manufacturer's 48" belt
