Piano Truck

[Vanderhoofven]

Dear Friends,

One of the colleges I tune for has a Steinway 45" studio that was being
moved.  A bump in the floor along the way broke off the left front caster.
They inquired as to the possibility of installing a piano truck under the
piano.

The APSCO catalog, page 34, lists three piano trucks for upright pianos.
#03545, #03540, and #03546.  Which one of these will be best suited for a
Steinway studio piano?  

Thanks!
