I just went out and looked, same thing.
I bought mine with 9k miles on it so I'm sure something could have been removed but I really don't think so.
Mine is all shiny still, like yours, and I have 80k miles now.
What is strange is the fact that there are no holes for mounting, only the dimple in the middle.
:thud:Found it, .......errrr I didn't. :thumbsup: Nothing was removed. It is a machined boss with a dimple in the lower crossmember traverse spring/lower control arm bracket to allow adequate clearance for the high pressure AC line.
Mine is just as polished with only 19K miles. :rolling: Being the original owner.........I know I did not remove anything. :thumbsup:
