What should I replace at the same time?
Where labor overlaps, replace the retainer clips with any panel removal — they are cheap insurance against squeaks.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2021 International LT was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2021 International LT?
First match the engine — each row shows which engine(s) the part fits. Then interior plastics are often color- and trim-specific — check the notes column against your trim level before ordering. The notes column carries position and trim qualifiers where they apply.
