I have one (my only TU56). the front casting is the same as for a 
dual-drive one, with the trasnport and heads fitted in the left drive 
position. There;'s a metal plate with stud fixed to it placed over the 
hols for the second set of motors/heads/controls with nuts and washers on 
the studs inside the unit to hold the blanking plate on.
