I'm selling a tail light that has one part number (140 820 75 66)
it's for a 99 s320

A guy just asked me if it would work for his car a 99 s420 when his part number is 140 820 75 64

I dont know why the part numbers would be different so i'm scared to say yes, but i was almost sure every tai light on 97+ w140s was the same.

So can i safely say they are the same?
