Belt measurements?

Hi,

I dropped by NAPA to pick up a couple belts for my 90 535i and for some reason they had a couple sizes listed. The PS belt only showed one listing so I picked it up, but;

FAN/ALT showed listings for 41-7/8" and 41-3/8"
AC showed 33-7/8" and 32-7/8"

Can someone help with the proper choice?

Your best bet is to look it up on http://www.realoem.com

And you will need to provide production year amd model. Production year can be found on the drivers side door jam. There should be a black tag on there with white lettering.
