Oh sure, but, those options mentioned are quite common along with the FS package. Just getting a 273 4bbl and a tach without it being a FS is fairly rare. Of the six '66 FS's I've owned (4 auto's, 2 4 speeds), all had disc brakes, and only one (an automatic) didn't have an 8 3/4. My non-FS car has all that gear too, along with the heavy duty suspension and heater delete. Strange car. I also had another non-FS one that was a 273 2bbl, 4 speed, 8 3/4, and drum brakes. Another oddball.
