Instrument Panel Bulb Sockets

Went to Cambodian Tire to get a couple of those sockets for my dash , 1 fell to pieces when I pulled it out and another was missing so I bought the last pair they had , flipped the package over and they were made for Standard in Taiwan .I have to go searching for another pack because I found 1 that was completely different in that the lock tangs don't stick out like the others to so it doesn't lock in securely weird , I wonder how I ended up with 1 oddball like that ?
