IMGTX- Did the engine remain at the normal angle or did you have to lower it in order to have the overdrive unit miss the floor board?
On A-bodies this is indeed what's happening, not sure on other models.
I had to
pound 'create' some extra space in the tunnel from beneath so the trans sat a bit higher on my '73 Dart.
I chose the easy way out, but it would be best to just cut open the tunnel, position the transmission properly, and then reweld and form the tunnel back around the transmission/overdrive flange.
