Question on floor opening for A T

I'm going the opposite direction. (plan on keeping all the parts in case I change my mind) If you need any measurements or pictures let me know.(not sure if the measurements would be the same as my 69 dart) I had welded the hole shut for the automatic shift rod a while back. (Was using a b&m ratchet shifter) so I'm not much help there.

Based on all the pics, it DOES in fact look like the shift boot was mounted and then the inside of the hole was just cut out to allow for whatever placement needed to happen.
