Ya, I agree. The good news is, that it should be easy to duplicate from the looks of it. I copied the url from the P11/B15 how to thread for an example of the bracket.
It's been a while since I did the P11/B15 swap, but from memory...the "b13 trans" shifter stabilizer mount is attached to the rear motor mount and the "P11/b15 trans" shifter stabilizer mount is fastened to the trans itself. I'm using "" 'cause i don't remember the trans codes off the top of my head lol Maybe I should snap a pic of my car for a better visual.
