ordered one last night, now I got to do some research on what size belts to use. Im thinking there going to be the same as the MPx pulley.
Alternator - 5040320
Accessory - 5040500
"Those are the Dayco Belt numbers I got from Modern when I got my UDP"
Should be the same for yours too

you won't need to change the alternator belt, because the alternator is on an adjuster bracket, so you can take out the extra slack you'll have once the new smaller adam.k pulley is installed.
32" long 4 groove belt is what you need for the alternator belt.

Wow, way to answer a 2 year old post
Here is the PN's I have for alt belt and Adam K. ODP -
"Gates KO40292 is what Adam K uses."
"According to Mike Guyer:
Dayco part# 5040295
or
Gates part# KO40295"
I think I used the shorter one ""292, instead of the 295.
