Factory option

1965 Mustang

The bench-seat option changed the front seating layout while preserving a sporty floor-shift and armrest arrangement. Body-code rows make it more traceable than most 1965 individual options.

The 17,016 figure is a MustangCarFacts sum of two reported later-1965 body rows, not a complete early-plus-late factory option ledger.

Factory option

1966 Mustang

The factory price list limits the full-width seat to hardtop and convertible body codes and excludes it from the Interior Decor Group, fastback, and console combinations.

The count sums the source table's 1966 calendar-year bench-seat hardtop and convertible rows. It is a body/seat population rather than a standalone option-installation ledger, and equivalence to 1966 model-year production has not been confirmed.

Market United States
Availability Available on 65A hardtops and 76A convertibles; unavailable with Interior Decor Group, the 63A fastback, or console options.
Advertised price $24.42 suggested retail in the March 1966 price list

Evidence note
21,397 hardtops plus 3,190 convertibles equals 24,587. The source table labels its columns as calendar years, so model-year equivalence is unconfirmed. The price list confirms fastback, console, and Interior Decor incompatibilities.
