Flexplate is not fits the torque converter

I made some reference lines through the centerline of some of the bolt holes. Then I took measurements so there would be additional reference points for anyone trying to draw the notch onto a neutral balance. 10230, which is basically the same thickness as the 10242. I will need to refine this later to clarify where to take the measurements, but it’s from closest points, not the center lines. Centerlines were only used to position the reference lines consistently. Also, this last picture is with “ENGINE SIDE” facing up.
