Is my '65 or '66 Mustang a factory GT?

Here are some items to look for. Factory GT's will have the following
in 1965-66:

 1. Build date after March 1965.

 2. A or K code engine (in VIN).

 3. Front disc brakes, heavy duty springs, sway bar and shocks (was available
    with other packages or in some cases individually-front discs).

 4. Factory dual exhaust (was also available with non-GT's and C codes).
    Will have correct floor and rear frame rail reinforcements.

 5. In 1965 they received a different glove box door than standard Mustangs
    and full gauges similar to 1966's.

 6. Grill lights (driving lights) mounted to the grill center with
    horizontal bars.

 7. Correct wiring harness and placement coming to and from the
    radiator core support to the light bar.

 8. Correct switch and placement of on the under left hand side of the
    dash for the fog light switch.

 9. Side GT stripes and emblems (no holes in fender for the standard
    MUSTANG script or running horse).

10. Chrome exhaust tips existing through the rear valance (round with
    chrome/stainless oval trim). Will show no sign of rear bumper guards.

11. Gas cap - standard Mustang on '65 GT's on '66 special GT gas cap.

12. No rocker panel molding so no mounting holes.

13. No quarter panel trim so no mounting holes.

14. No special interior or wheel packages required.
