I worked for a g/box reconditioners for a while, most recon g/boxes just needed bearings and synchro's. If it was more than that (gears etc) they were not viable and the good parts used for spares. We used to buy a lot of low milage g/boxes out of crashed cars with broken cases for most of the internal parts.

Modulators gearbox was shagged last year, we just put a recon box on for a few hundred quid.
Once you price the bearings, seals and gaskets put some labour on, I wonder how they earn any money out of it
