Mine is the late one with the plastic bush.
I would like to replace this bush and have one on order.
i have read that you dont need to remove the old one, just drift the ne one in on top.
is that correct please?
Mine are 11in and sweep corectly.
The answer lies I think in the arms.
The rh one is straight and the left slightly cranked.
I had 2 cranked ones on and yes the sweeps did not meet.
Look at old images and see what mean. So many I see are incorrect.
