So I'm kinda confused. I've found 3 different part numbers for what seems like the same thing. I'm trying to find the stock delco part number for front pads on my 2002 ls1 SS.
part numbers that I have are:

18026165
18038574 <--- I think this number is for "duralasts"
18026298

Which one is correct?

Thanks
