Did 1967-1968 Chevy C10 front sway bars use 4 D type bushings?

[HeavyHauler]

I was wondering if the factory front sway bars for 1967-1968 Chevy C10 used 4 D type bushings that mounted the sway bar?

I see larger performance sway bars being sold that use a different type of end link bushings that mount vertically on the lower control arms rather than using a D bushing on each side.

Does anybody make a larger sway bar that uses the simple D bushings in the factory location if that is what they used?
