55-59 cabs are all the same in this area.
just for giggles, if you really want a pro look around the floor mounted items you can have someone with a walking foot sewing machine sew binding on the edges of the holes you cut in. it finishes the edges well. prolly wouldn't break the bank either. then, because the hole may be a little larger than it was you may see the felt/underlayment/floor metal so, before you install the carper over those areas slip a same colored (or black racer tape) piece of dull sheen lighter material under the dimmer switch or whatever before you screw them down. this will also help with fibres getting into the mechanisms of the moving parts like dimmers or through floor pedal rods. some 2 sided tape on those little pieces will help keep them in place
