thats for a normal sierra and garnada prop not xr4x4 or 4x4 cosworth
the xr/cosworth has a bearing in the middle which locates the the centre of the prop and the gearbox

i fitted one of these as in the pic but a rubber one got a very bad vibration at speed and then had major problems when tried to drive through it it snapped the end o f my gearbox off

these are not for 4x4 cosworth trust me not to shore on 2wd
