its on a 88 model twin cam seca (ae82), the toyota guy said it wouldn't be worth while 2 replace them as re-con 1's would only cost a fraction more. if i remember properly he said around $180 plus 1 hour of labour? i was actually thinking of either reconditioning my gearbox while I'm at it or fit the 20v box, anyone have experience in this? how much roughly would a workshop charge? any recommendation in north sydney area? thanks 4 any help!
