Qty is how many the assembly uses, as the manual lists it. Our price is our online store's price: Buy online opens that part on secoparts.net for card checkout. Typical is an estimate from the government catalog price and what we have charged for similar parts — not a quote. Gov't list price is the government catalog (FEDLOG) price, a public reference, not ours. "Fits" comes from the manual's usable-on codes; a line without codes applies to every model.
