It took me a while of starring back and fourth from my valve body to the B&M instructions on my phone but I got it figured out...
I think I finally understand, appreciate the help so far!

I measured from the casting to the very end of the line pressure adjusting screw and it's exactly 1 7/8"'s... I'm still going to measure from the casting to the adjusting plate... According to the B&M instructions I have 3 options? I'll probably go with the heavy duty... It's stock but the converter is HD and the clutches are HD...idk...

Here's a picture of the style cage and bolt I have in my 727...

The cage is a bit off in the picture because none of the screws are tight, waiting on a new torque wrench!
