With the factory Tow package (A35) you got the following:
Auto trans, 3.23 rear gears, HD brakes, HD stop lamp switch, Variable load turn signal flasher, High capacity cooling fan, maximum Cooling, auxiliary trans oil cooler, HD suspension, and HD or "trailer tow" wheels. NA with 440-6 or hemi engines.
I've often wondered what my B'cuda towed, figured it was either a small boat or a pop-up camper. Someone ordered themselves an unusual car when they ordered this one...FC7, black top and interior, 383 2 bbl console auto. AM-8 track, light package, road wheels. Standard flat hood.
