X-Code Lsd Dying--How To Source The Repair Parts?

[redvalkyrie]

My vintage x-code 5.6" TRD LSD is beginning to show signs of wear. I've located the correct TRD part number for a rebuild kit--40107-KP611. However, it's listed as discontinued. However again, just because a part isn't being made doesn't mean that part can't be found on a shelf somewhere.

 

I know someone is going to suggest swapping in a AE86 rear and it might come to that...but buying a complete are axle assembly and adding or rebuilding a LSD for it, is going to be big bucks. The 40107-KP611 rebuild kit is listed as being about $150 US.

 

Can anyone lend some advice on how to communicate withTRD Japan or point me to a third party that is good at hunting parts? Any help would be appreciated.
