Torque converter

[79ChevyBu]

looking to get a new torque converter for my turbo 350 transmission. I know this says it fits a turbo 350 but will it work, http://www.summitracing.com/parts/BMM-20402/Application/?prefilter=1
the thing that is confusing me is I dont know what torque converter bolt circle means. My motor is a sbc350 with 3 bolts holding the converter to the fly wheel.

thank you

its the diameter of the 3 bolts in the circle, most flexplates are drilled for 2 different sizes.

So this might be a dumb question but how do I figure out what mine is.

If your flexplate has 6 mounting pads, you have both.
