wtb escort diff complete preferablly NSW

g'day guys
My borg warner 68, 3.89 (toy diff) is getting noisey/chatery so im wanting to replace it with a stock mk2 complete unit 3.54,3.77 if any one has one laying around in resonable road going condition for my RS.
I have a ford courier/b1800 diff here but it has 4.11 gears and needs abit of work to get up to scratch so the stock escort diff is an easier/quicker option.

NSW preferably.
Im in the southern highlands

cheers
Dave
