my center bearing needs doing soon Was recommended a place
Gibson driveshafts Edgeworth nsw $685 to modify the shaft to fit a replaceable uni joint including new rear rear section
add $187 if trans end rubber coupling is needed
add $110 remove and refit if needed
have not had the work done but they have been around along time and deal with all types heavy equipment.
I also saw on ebay from B & Z auto parts repair in Bankstown nsw same thing for $600 without the trans rubber
just pickup at fit yourself
