SAME PART NUMBER, DIFERENT OME SHOCK! Could anybody explain that?

These are the part numbers for the JB74 or Gen4, the thread starter has a Gen3.

Dear Fordem,

I was talking about this problem with a friend that worked in consumers right in Brazilian Justice. The first thing he said: _If it is a part counterfeit, the size probably will be the correct size! Together with your observation, that jimny was not sold in USA, and the litle probability that such a small market could interest a counteuterfeit operation,
Your hypothesis, of a Frankenshock is probably the case!
However, the shocks were bought in february/march 2020, in the strating months of the pandemics....
I made a call to ARB USA, they told generic things. I ask them to answer my request previously sent. No answer at all.
Best regards!

Still struggling to be helped by ARB. Now, someone from USA said 029 schocks were not available aanymore. (029 is still present at OME application catalogue 2024). They are offering me a   OME Shock 63398 that  would be the best replacement, However, I was not able to find this shock in their Application guide.
Please, anyone knows anything about OME 63398 shocks ?
Best regards
