I did this last year.
The swivels are held with welds down both sides.  As far as I remember a
sawzall will probably have problems with the the blade bottoming out.  If
you have it, a much better tool would be a right-angle grinder with a
cut-off wheel - but sparks galore of course.
Also need a 13mm wrench to unbolt the swivel plate.
