I found out the hard way sort of........my mid plate was in a batch of other stuff I got from the secondary market , but I was more than a little surprised when even a hammer wouldn't make it work.
I don't know if anyone makes one , but you could use about 75 % of the 727 one as a template if you want.
Hold it up to the trans and see where you need to cut , get a sheet of .090 mild steel and you should be cooking with gas.
Let me know if you want to try it and I can ship the plate / template to you.
Just send it back when you're done.
