This is an old thread but thought Id contribute.
I had the same problem, so I cut out the middle 5 or 6 ribs, and had the two halves welded back together. Then I just ground down the high spots, bondo filled the low spots, and primed, painted and done. Looks factory, but about half the length.
Just make sure you dont cut too short or your fingers will hit the dash, and hope you dont get in an accident, because a poorly welded can will break instead of "crush", and it could impale your chest.
Not a pretty thought.
