It is a different box on the mk1 a gertrag they all also suffer with the driveline shunt so dont be alarmed.To fit a short shift requires a kit you have to take off the shroud and access the top of the gearbox.For shorter gear action saw about an inch and half off the gear lever re tap the thread or fit a le mans style gear knob,Richbrook do one as previously mentioned at about the third of the price from morgan.THE big knob wont come off in a hurry and will require sawing off best way from the top down either side of the lever, stick a bit of towel around your alloy ring surround just in case of misshaps simples....
