BTW, Just had a call from the bloke who has the diff... He has lined it up against an MX83 unit (non-LSD) and, although he reckons they are virtually identical, they are just different enough so that the Supra item won't bolt straight in. My question, then, is this: Can I get the Supra LSD, and an MX83 non-LSD housing, and bolt the LSD internals into the MX83 diff housing? LSD under consideration is from an MA70 Supra.
I need some sort of definitive answer on this pretty soon, as I need to make a decision on whether or not to go ahead with the purchase or to wait (probably forever ) until an MX83 LSD becomes available...
