Default C6 Leaf Spring Identification

I picked up some used leafs a while ago and want to confirm what they are before I install them. I figured you guys would be able to help with this. There are two numbers, one engraved/molded into the spring and one on the sticker with the bar code, I listed both below.

Front: Engraved 22171750, sticker 22178729
Rear: Engraved 22200944, sticker 10302917

Any help would be appreciated.

The front is definitely a C5Z front spring. Unfortunately I can't identify the rear spring number by either the engraved or sticker number.

Same 526lb, but not sure if it will fit - there are threads where people ask about it, but no 100% clear answers.

However I do know that the rear c5 and c6 aren't interchangeable,

Here is a couple of pics. I am not sure what a front C5Z spring looks like...

OK I figured it out. Both numbers have been superceded by GM.

The front spring number is for FE3 sport suspension manual and automatic transmission from 1997-2012.

The rear spring number is for FE3 sport suspension manual and automatic transmission from 2005-2012.
