1 of the Hungarian guy, who makes race gearboxes. It was built for a rally car in France but the car crashed before the gearbox was installed. I will send more details by email for rallygarage user.

Hi Szuti,

do you know which kind of gearbox it is?
Straightcut wheels? Wheels width?
dogbox?
to operate with standard cables?
Where is the gearbox to be seen?

It is not sequential shift. It is an H pattern shift straight cut dog engaugement transmission. Final drive is straight cut as well. It is very good. Need a stock ST205 transmission case to complete the build. I don't think this price includes plated diffs that would ideal for rally. If it does then the price is a very good. We have one running in Calgary Canada. Good price either way. Will transform a drag racer or a rally car into something worth keeping.

Too bad there is no true sequential for our cars. Shifters only.
