PX Steering stuff

Have started (well a friend has, I made brews!) on the fork spraying & fitting of T5 mudguard to PX.

Unfortunately during the removal of the dust shroud and what the Haynes manual calls the „Lower Cone“ both items were damaged.

I can find the dust shroud on the SIP website, but can’t find the lower cone, can anyone tell me if this is available seperately, where it is, and what it’s called?

Or…

Is this included in:

Bearing kit steering column
V50/PV/ET3/PX/T5 '66- PIAGGIO/
GILERA 50-180cc, lower
Art.-Nr. 90110000

Cheers for your help in advance.
