Limited slip diff plates source?

I have decided to take the plunge and replace the welded original differential case on my 91 TR with a billet case from Newman. Assuming that 51,000 km have worn the original plates somewhat, does anyone have a source for OEM friction and steel plates used in the case and perhaps even the Belleville springs?

I understand they are ZF parts? Does anyone have ZF part numbers?

Regards to all.

 

Thanks. My intent is to gather all the bits before the car is disassembled, to minimize down time. My understanding of the LSD is limited; I assume that when rotating one rear wheel by hand, the other wheel should rotate in the opposite direction, as with an open differential, as the LSD plates on both sides are engaged equally, thereby sending the torque applied through the differential?

 

Thanks for the offer of the plates. Will look and advise. Just so I can check tomorrow (my car is currently on jack stands), with the transmission in neutral, if I turn one wheel forwards, the other wheel should turn forwards as well? Not in the opposite direction as with an open differential?

What if I place the car in gear? Any difference?

 

I checked last night - exactly what I found. In neutral, they spin in the same direction. In gear I could not make them move. I suspect you may be correct, perhaps new plates will not be needed. When it comes apart I may post measurements and photos.
