67 formula s barracuda 8 3/4 standard or option?
Here is the specs page from the 1967 Barracuda brochure. According to it, with the the 273-4 engine, the manual trans got an 8.75 3.23 standard, the auto came with a 7.25 3.23 standard. Sure-Grip was an extra cost option in all cases (see the paragraph under "Transmissions" — the table is a little confusing — when it says "std." in the Sure-Grip column it is referring to the RATIO that is standard when you order the Sure-Grip, it is not saying the Sure-Grip is "standard" for any drivetrain combo). Elsewhere in the brochure it describes the Formula S package — it doesn't say anything about it including any axle type or Sure-Grip. That said, it is very likely that dealers often "loaded up" Formula S cars with the extra-cost performance options, and of course original buyers often ordered them as well.
