Did the job today - only needed to remove the air box, not the intake manifold like the original instructions mentioned.

With that said, the idler pulley in the middle with either the offset or centered hole, that is rather inexpensive at $25-$30. However, the two tensioner pulleys are hella expensive because they don't sell the pulley separately. I did manage to pull it apart afterwards.

Pulley Dimensions -

1. OD - 70mm
2. ID - 16.95mm
3. Width - 26mm

Dayco has two pulleys listed -

Pulley #89144 -
OD - 70mm
ID - 17mm
Width - 25mm

&

Pulley #89133
OD - 70mm
ID - 17mm
Width - 24.5mm

Both said they can be used for 6 rib belts. They list for ~$25 on Amazon. May be a cheap alternative than replacing the entire assembly which isn't needed.
