It's a 4-Speed box and sadly the clutch-housing is cracked.
I will weld the housing (going to be fun...) and see where the shifter would come out of the floor.
Are there any pictures of the gear linkage in the performance parts manual? I wasn't able to get a copy yet...
The engine is only missing the distributor and the crankshaft-wheel and it was pretty cheap (125€ for engine and 2 gearboxes). The other one is complete and running inside a Bedford CF (we're getting the whole car for one crate of beer), so we got enough spare parts for the build for the 2017 race.
