torque converter bolt pattern?

I am looking to purchase a TCI Street Fighter torque converter to connect to my TH400 on my 72 C20. However, there seem to be different bolt patterns available on the converters that are listed as compatible with the GM TH400 for 1972. How do I know what bolt pattern I need? Thanks for insight.
