Fog Light Bezel 4cyl vs 6 cyl - huge price difference, same part?

When I purchased my truck the passenger side bezel clips were broken on one side so I'm looking for a replacement bezel. On the same side the fog light also has water in it and the reflective layer has flaked off leaving yellow plastic.

I'm trying to purchase a replacement bezel first and there are 2 sets of what looks to be the exact same part. The only different in one is 2x the cost and says 6-cyl vs the other which says 4-cyl and is cheaper. The two look identical to me, any ideas?

12-14 6cyl version $55

11-14 4cyl version $20

 

It isn't engine dependent - it is chrome vs not chrome. -04020 is black -04030 is chrome

Awesome, thank you!

 

And when I say chrome, not the whole thing - just a ring around the light:

black -04020

 

chrome - 04030
