Dayco book called for a 47 and 1/2 inch belt (15475) but it was too long. A
45 and 1/2 inch belt worked fine ( 15455). The last three numbers in most
belt part numbers is the length. A stock blower belt for our cars is 56
inches,  or a Dayco 15560. The first numbers refer to the width. In Dayco a
15 series belt is narrower than a 17 series belt.

The "15" or "17" refer to 32nds of an inch (width).  Many other belt
manufacturers use the same or similar numbering systems i.e. Goodyear,
Gates, etc.  Napa's #s are totally foreign.  Autozone sells Kelly
Springfield belts, which use the same kind of #s.
I've sold a lot of belts over the years.
