trouble getting spare parts to head to rally!

I have trying for over a week to get correct parts (Water Pump,Idler Pulley and Belt tensioner)for my m1078A1 LMTV with 3126 cat engine number 7jz00087, to no avail, the CAT computer at dealer shows a water pump that takes a vbelt my complete engine runs off of one serpentine belt can someone direct me into the correct part numbers so I can just go to cat dealer and say i need these part numbers or is someone on SS that has these parts.

Thanks Marty

I have complete v belt upgrade kits for the 3126. Maybe your truck has the kit. I can try to see if there is an inv in the kit tomorrow. Whats your truck serial number I may be able to look that way too.

I ended up pulling everything getting numbers off the parts crossing them i here they are;
This is for the 3126 cat with all serpentine belt system!

do you mind spacing and or punctuating some way so this is more readable. Hard to tell what goes with what with it all run together. Also if those are intended to be links they do not work.

Much thanks.
