$115 is still one third the realistic street price for the one in oem packaging.
If you have prime it ships free, I couldn't find one in oem packaging that I didn't have to pay freight of $30-40 . So when you factor in freight it is closer to one quarter than one third the price.
The only indication I got from the $83 Amazon deal was not %100 the oem kit was the hardware (not oem mopar fasteners) and the instructions (with mopar publication number) was a photocopy.
I've bought a lot of mopar factory parts and accessories and the fasteners and instructions are consistent.
One can only speculate where these came from. It is almost a given that Mopar oem supplier for this part is/was Chinese. So one way or another you know a Chinese manufacturer had/has the data file, the tooling .
The sudden abundance of these things in the secondary market feels inorganic and unnatural.
Maybe these things failed QC or were otherwise returned/rejected/undelivered and the Chinese are selling them direct to the consumer. The seller names are all the random alphabet names (with no corresponding english translation) characteristic of Chinese sellers.
I don't know.
I do know that for anywhere near $100 it is a good deal
