Torque converter bolt pattern?

Good morning everyone, I have a simple question that I have a hard time finding the answer to. What is the bolt pattern spacing for the torque converter on a pontiac flywheel? I thought it was 10" between the three bolts, but I cannot confirm.
I am about to install a 200r4 trans and need to get the appropriate 27 spline converter.

Thanks for any help

Many Pontiac flexplates have a dual bolt pattern, so that you can use either the small or large GM pattern. The small is 10.75" & the large is 11.5". If yours has only one pattern, you can buy a new dual pattern flexplate fairly cheap.
