After cleaning I see where the thin shims look like there galvanized and are on both springs.
Numbers are
3722293. 36369. 020 4
Both sides are the same
There's an active thread in moparts Q & A about factory leaf springs and part numbers.
Could ask there.
I'm not sure if the spring part numbers in the books are the same as the stamped numbers. Could be a digit off or something like that.
This happens with alternators as well. But for those there's bulletin explaining that.
*If you're not on moparts and/or don't want to join. Post the picture of the stamping, and the car info (year) and I can ask.
