Delphi Front Struts?

[tlsnokuyeulb]

According to my production code I should have ACDELCO 580-431 front struts, but upon inspection of mine, they are Delphi struts. The PO never replaced any suspension (I'm the 2nd owner). Did Delphi make oem struts for these things ever or have I been missing out on OEM ride quality? I have the z55 suspension. Thanks.

I just replaced an original z55 strut on my 07' LTZ and it was a delphi, but the replacement was acdelco
