OK all.
I've searched & searched and can't find the answer so I'm gonna ask:

Does anyone know the Power Steering belt size for installing with the AF/X UDP?
2 belts come with the pulley: Alternator and Power Steering with AC. However, I don't have AC in my car.
This is my daily driver so I can't afford to keep going back & forth to the parts store trying all different sizes until I find the right one. I called Howell Automotive and they didn't know (they only know the belt size for the one with AC).
I tried calling AF/X but both of the phone numbers on their website are fax numbers.

Any info is greatly appreciated.
Thanx.

just use a string and wrap it around like the belt will go, then measure the string... That's what I did when I removed my AC system... Make sure you have room on the power steering adjustment stuff so you can compensate for it being a hair off...

with no tensioner pully and the afx udp, its a 5rip 38" belt.

I used a 38.5" belt and it worked fine to bypass my AC and just use the power steering. Autozone can hook you up. I used Kelly part # 385K5 belt. Also could be under # 5PK0980

98 RS M/T - CAI w/K&N Filter - AFX udp - 2.5" Catback Exhuast - Symborski Shift Kit - Energy Suspension Inserts -
17" wheels & tires - Rear Disc Conversion - and now 1 broken motor mount!!!!

Thanks you guys.
I actually figured it out by taking the stock size and reducing it by the same amount that AF/X did. I also took the advice of someone else on here that said the supplied belts were too big and got shorter ones.
For example:
The stock belt for PS with AC is #K050510 (or eqivalent # by brand).
The AF/X supplied belt is #K050500.
The "recommended by (can't remember his name)" belt is #K050490.

I found my stock PS only belt to be #K050400. So I assumed that:
AF/X would supply a #K050490 and
"whoever" would recommend a #K050480. So I ended up ordering that.
I also grabbed a #K050485, just in case.

It seemed right at the time, and now that you guys have responded I'm even more reassured that I got the right one.

Anyway, thanks again for the help.

Check that, guys,
I ordered a #K050380, not 480.
