Valhalla or Lingo power supply for older LP12

Hello, 
A few weeks ago I received an older LP12, serial # 026xxx that has a simpler power supply, the bar that is attached to does not have all the holes to attach a Valhalla power supply.
I bought a lingo power supply to use with this table, but someone mentioned that the motor will not be compatible with the Valhalla / Lingo set up.
Is this true? And if it is, where can I obtain a new bar and a new motor? I prefer to do the change myself.
If anyone here can help me with these issues it will be beautiful.
thanks so much and happy holidays to all
best regards.
Mario
