Is there a way to tell if my OPDA has been changed?

I bought my LJR 2nd hand. I am reading how a OPDA can damage other things when it fails. I was wondering if there is a way to tell if mine has been changed to the updated Crown. I looked at both and they look the same. If I can't find a definite answer how to tell the difference I will just order one. $110. No biggie but I have so many small things that cost $100+. It adds up

If you replace it, make sure to not use the sensor (camshaft position) that comes in the Crown kit, re-use what is in there now which is hopefully the OEM Mopar.

I've read, and found on mine, that the OEM one had a sticker around the collar (near where the plastic cap closes) that reads something similar to "LKI Inc" or something like that (looking back at my pictures I didn't take one of that). None of the replacements do.

It's worth just popping out to check the wear on the teeth either way, if you see wear it's likely OEM.
