It'd be unusual to replace all the gears, they don't really wear out like other components in a gearbox do. The only ones that usually need replacing are the final drive (they strip), and sometimes 2nd (worn engagement dogs) or third gear (thrust damage). The cost would be inhibitive to replace all gears, you'd be better off either buying a second hand box and rebuilding that, or buying a brand new complete gearbox, or even getting an aftermarket gear set from gearX or something. I'd get it checked out 'on the bench' so that it can be properly quoted on. James at Extreme Project World is in Sydney, and is a trader on here who rebuilds them regularly.
