A-727 small metal debris in pan - rebuild?

I've found the B&M shuttle rod mod in the instructions for 10225, pls see pic. It's interesting to see the punishment that this rod (assuming B&M or similar) has received in my VB, considerable force needed to deform the rod in the previous photos.
My new concern is whether I have the original Chrysler separator plate or perhaps a B&M or similar substitute. Is there a reliable means of identifying the Chrysler plate?
Maybe there is no concern, if the holes sizes are checked/modified as per the Transgo TF2 instructions, it could be any plate?
