Just got quoted $600 to replace the Synchro rings, Don't know about the condition of the blocking rings and dogs. So who knows this could be fun, If anyone knows anywhere cheap in Victoria - Melbourne area to get work done Please list here!
I would rebuild the whole box while your at it . But if he only replacing whats worn then thats not a bad price .
Aye same, always been told if one of the syncro's are gone its not too long before the others follow.... rebuild the lot while its apart, save $$$. Also you might be able to message forum member Tektrader, he is in Melbourne and works on zeds.
A complete rebuild should be around $1200-$1500. Hard to justify the expense when you look at the price new series four boxes are going for on conceptz.
