my 2003 MCS stock pully belt is slipping really bad.

I just left Napa and they claim the belt I need is a
NAPA #060415 42 1/8
it looks just way to small so I didn't buy it.

so I went to Autozone.com and I see many belts listed for my car, and several of them are different lengths.
1 of them says 54.750 inches a different one listed for my car is 41.5 inches.

Orielly's.com also shows three different belts inluding the 060415 & 06408 & 060547

Help. I need the belt today, what length do I need?

edit: WTF, I was trying to edit my own post not bump it...

sorry, mods can delete this if they want.

 

The OEM belt for our 06 MCS when it was stock is the Continental 6PK 1388-(1388mm or 54.64 inches long). Good luck.

 

+1 to 1388mm length for stock belt.

 

I am pretty sure that 54.64 inches (1388mm) equates to the 060547 belt. You can check with the parts store but I think the 060547 numbers mean 6 rib belt that is 54.7" long.
