Price of 8.75 option for 1967 barracuda

I have had a lot of 67's. These are just car I owned
Big block every one had 8.75,
4-spd every one had 8.75.
auto trans - w/formula-s, I have never w/o 8.75.
273 4-bbl commando, w/o formula-s, w/auto didn't have one.
273 2-bbl non formula-s I've never had one with 8.75, 2 had suregrip with 7.25.
Never had one with towing package to comment.
