Need a cross reference for brake pads

[jspin91]

Hey guys, Im trying to find a cross reference for new brake pads I bought thru AC Delco for my 05 GMC Sierra 2500 HD 6.6L 4x4 years ago which are still brand new by the way but no hardware, just 4 pads. All have part# ACD A3800 FF. I’m only asking because I’m selling them and need deeper specifications as to which vehicles besides my own they are compatible with. 

Edit: Added picture. Little bit dirty I know

Various auto part web sites will have a tab for applications for individual parts.  You should be able to find that acdelco part and then be presented with a list of vehicles it fits.

Yeah, I tried sites like AcDelco, Rockauto, Autozone etc. with little to no results. Also sent e-mail to ACDelco as well. I thought I’d post here too in the meantime but we’ll see..
