I can help out with good prices on new parts just send me a PM
if the LSD had blown to pieces and it's destroyed seals etc etc I dare say the crown and pinion gears may be worn and if you're going to do it, do it right but better than a factory new item which is average imho in the ute, sedan no worries but the ute diff set up is a bit chit lol
new TruTrack, crown and pinion gears,bearing kit,shim kit seals etc etc and just get your mechanic to fit it all up
