You dont need to replace the small bush 65 3377.
You might not need to replace any of it. Usually the oil drips out of the cable where it joins the light alloy ferrule by the gearbox which helps keep it out of the speedo head. You could check the cable after some use and see if it is oily.
If you think there is too much then you could replace but I am not convinced that the pattern bushes are much better than an old one for fit. The driven gear has an oil scroll to help keep the oil out of the cable, it might help a bit but the later driven gears have a fragile O ring fitted which helps a bit more.
Photo show later type bush and driven gear with O ring.
