I have a 1990 Mitsubishi GTO, gearbox is out and sitting in the workshop. Told the output shaft is worn, transfer case needs to be replaces and the synchros and bearings also need to be replaced in the gearbox. Was looking at getting the gearbox from kormex
kormex trans parts
as a changeover but the guy doing the box is looking to having everything rebuilt here in Australia. I'm not sure what option is best, I am looking at putting more power into the car as the years go by and I am afraid that if I'm still stuck with the 18 spline it'll just break again. Any words of wisdom woud be greatly appreciated.
