Formula "S" question

ALL '66 Formula S's came with a 273 4bbl engine with HP internals, dual point distributor and dress-up trim; front sway bar; 6 leaf HD rear springs; tachometer; 150mph speedometer; low back pressure single exhaust with chromed-tip resonator; 14X 5 1/2 wheels with 6.95/14 blue streak tires; and "S" fender badges. Like it's mentioned above, there will be a 7 under the uppercase F on the fender tag. It will also be on the build sheet if you're lucky enough to find one.
