Will GM 200r4 work with factory floor shift location?

Found another small problem that can cause a major delay during installation. My barracuda has a 360 magnum exhaust manifold on the passenger's side. Because of where the manifold exits my exhaust pipe passes very close to where the TCI adapter will be. On a 318 there is a square boss that sticks out on the passenger's side near the back of the block (see pics). My exhaust pipe passes just below that square boss. Using my dummy block I installed the TCI adapter and marked the adapter in the area that the exhaust pipe is located. See PICS.
Then I took the adapter and placed it on the tranny and found that the 2004R tranny has a large bulge just below and behind the area where the square boss projects from the engine. So to be safe I plan on trimming a good chuck of the tranny bulge so that I won't have any exhaust clearance issues when I install the tranny.

The first four pics are with the adapter on my dummy engine showing the square boss and the area that I might need to trim on the adapter.
The next two pics are of the adapter on the tranny showing the large bulge and the blue magic marker showing where I plan to trim the tranny housing.

The last pic shows the view from under my car. It shows the exhaust as it passes behind and below that square boss.
