Correct. Cut the opening so that there is still a 3/4" to 1" flange to attach the new trans hump. You can simply use self tappers, or drill larger holes in the base flange and use threaded j-clips, or install nutserts in the base flange for bolts to thread into. Having the removable cover is super handy too.

Gotcha! last night I ordered the cover from Auto Metal Direct so I will see when it gets here.
