Belts and pulleys part numbers help

[treehan77]

going nuts trying to make sure I get the right parts to do the serpentine belt, all idlers, pulleys etc as well as the ac belt and tensioner.

are these the right kits? Anything else I'd need?

Can't seem to find part numbers for everything in here, and the second kit doesn't really say what part numbers it contains.

These are the 2 belts and tensioner that I put on my 06 back in Sept 2018.

I cross checked on Rock Auto and other sites to make sure it was the correct part numbers. Forgot to mentioned that @HiHoeSilver helped me with some of those numbers too. Thx man. @treehan77

Here's some of my info...

@treehan77, your serpentine belt length will depend on your alternator size.
