Auto to manual trans tunnel revision?

[72 AKCharger]

I’m Putting a 6 speed TREMEC into a 72’ Charger. Will I need a new tunnel entirely since it was an automatic? Or can I just revise the original tunnel and stuff it in there?

I believe the torsion bar crossmember and transmission mount areas will be the points of interference. Measuring will help you figure out what's needed. Is the automatic out yet? Is the project a go, regardless of issues?

Yes the auto trans and engine are out. No crossmember currently on car.
