I am sorry to say mine does not have the handling packageWelcome fellow Bill with a Mach 1 ---- looks like we both have the same year and are fortunate to have the elusive " Handling Package!" Fun site and great to have another Mach 1 Mustang Maniac on the TMO Forum.
your observation was correct the car does have the performance rear spoiler, but without the gurney flat. I am not sure why car came with the performance spoiler.No worries I thought the pic of your car showed a larger wing..........my bad.
