Catalog gaps — Monte fitment

1. Every row is one thing to add to the fitment catalog — a car, an engine, or a few model years. The row says which, and exactly what to add.
2. Open the row before you add anything. Inside you see what our catalog already holds for that model, engine by engine, and a list of similar names we carry — that is where the same car sometimes sits under a different spelling (Silverado and Silverado 1500, F-150 and F-150 Heritage). Nothing here is proof on its own; the point is that you can check.
3. Mark what you did — Added, Check or Skip, plus a note if it needs one. Marks are shared and saved, so Summit sees the same board.
4. The search at the top is the whole catalog, not just this list: look up any car, any time, to see what we have on it.

Where the list comes from: our catalog was compared against EPA fueleconomy.gov, the US government's fuel-economy database, which lists every model, engine and year sold in the United States. Rows marked internal check of our catalog came from comparing our own data against itself — no outside source — so those need a second look more than the rest. Electric cars are excluded; hybrids are kept and labelled.
