I suppose the current ashtray swivel pin is not the freshest anymore.
This because the fitment is not so tight anymore as it was when new.

Be aware: The original fitting set uses spring washers to give the ashtray the soft resistance when siveling.
The disadvantage is, that the spring washers will scratch the surface of the ashtray in such a way, that the item is often not usable for reconditioning.

This swivel pin is made of aluminium and comes with suitable Nylock nuts and washers. This gives Your ashtray the 'like new' feeling when positioning.

It is required, to widen the hole of the ashtra to exact(!) 8mm - best to pre drill and then to ream the hole up to the exact diameter. !!
This because the hole in the ashtray is not round anymore after these long years of usage.
With this set Your ashtray can be moved to the desired position with the 'like new' soft resistance without any scratching the ashtray surfase.
A instruction manual is included in the set.
