What still deserves attention is the notes column on each part, where position (front/rear, left/right), trim and production-date qualifiers live.
Every part across the 7 categories shows its brand and manufacturer part number. Use the number to cross-reference: match it to the part coming off the vehicle, compare an OEM-supplier part against its aftermarket equivalent, or verify a shop's estimate line by line.
