It's rally car and he's looking for claw transmission gearbox (I'm not sure what's the English name of that, that's why I descirbe it: gearbox with straight teeth, to start You use clutch only for 1st gear, after that You can change gears without using clutch).
If You have one to sell or You know somebody who have one for sell or someone who's producing them- please let me know.
