67-72 factory sway bar sizes thru the years/options

stated as 15/16” measures 0.95~” which Is slightly above 15/16” but figured that 15/16” was the “nominal” dimension intended,

Reasonable assumption. So it actually measures the same as the other 69 bar.

to my knowledge there's only two sizes of 67~72 bars: the small block bar and the larger big block bar; commonly referred to as 7/8" and 15/16

As for SB vs BB the parts book only shows 1 bar part number per year so I don't believe you had a choice based on engine type.

If enough 67-69 a body owners reported their KNOWN stock bar OD we could probably put this to bed.

Time to crawl under those survivers with a caliper!
