ok ..I'm gonna step in here before some poor guy mangles his car...

IF you cut the anchor..you better have prior to that welded a new support/cross section in.
OR/AND taken the load out of the torsion bars so the cross member does not tweak/move.
floor pans that have dimples/grooves are there so they do not buckle, other wise there would be a lot more cross/sectional members to reinforce the floor of the car and along with that, more weight.

remember..that torsion bar anchor/trans cross member is apart/attatched to the suspension.

if you start beating on it with a hammer, no matter how small, it will shift something due to the force required to ding the thicker cross member.

Just so we are aware here.
