Is this the same package they put in the Turbo Birds.
2 friends had those and when they applied some effort to modifying them they did haul the mail.
I believe the SVO tune was a little hotter as well as the suspension package but the hardware was close if not the same.
I always liked the SVO Mustangs. I had a 84 turbo XR7 Cougar that car was a whole lot of fun. Traded it for my first SHO.
