Trans tunnel Question

Someone will correct me if I'm wrong but here goes...
You will need to turn the center section of the cross member around from where it is now to accomodate the trans support. 2 of it bolt holes wont quite line up. If you force it to fit with a floor jack your trans will hit the tunnel thus the tunnel will need a "hammer" adjustment. Alternatively just file out the holes in the support. File 2 holees enough, all 4 holes equally, or adjust the tunnel, is up for debate.
