Hello,
First of all cheers for everybody as I´m new here.
I have a gearbox which I believe is from Ford Escort Mk3 RS Turbo S1 (circuit) racing car. It is a 5-speed dog engagement gearbox with viscous LSD. Originally it has a cable clutch.
Now the gearbox is broken and I´m very keen to have some information about it. Manufacturer? Model?
Here is some pictures of gearbox to be identified:
