Having issues with ASP pulley and gates A/C belt.
This belt is too easy to install for it to be a mistake of mine.
I measured the belts and theres a 1.5" difference in the two. How can the K040378 belt not fit if thats what everyone is using?


What am I missing here???
K040410 = 41"
K040378 = 37.8"
Maybe get a belt right in the middle, like a K040390?
thanks!
