New SFI magnum Flex plate coming soon.

This was my understanding for 904 as well, but I don't have a 904 torque converter to mock it up. LA or Magnum just changes the balance weight, and 904 or 727 changes the diameter. I could be wrong.
I messaged Ryan a few times my self and never really got any aware. My stock 5.9 magnum flex plate was cracked and I needed a new one. I was wanting to install a SFI one because my 96 dakota will run low 7 in the 1/8 mile. But not having any luck I just installed another stock one. I am using a conan 8 inch converter with my 904 transmission. All I had to do was file out one of the bolt holes like everybody else does. Anybody know why B@M stopped making them? Also could somebody make a template for me. I would pay for shipping etc. I mean I was going to buy a neutral balance B@M SFI and cut out the spot for it to work with the cast crank 5.9
