TR7 / TR8 lower ball joint dimensions

[Tacchino]

Is there anyone out there that has a TR7 /TR8 front ball joint lurking to hand?
I'm trying to get a few dimensions before I plunge in and buy several!

After the following :-
- base diameter - largest diameter
- diameter of raise serrated portion
- diameter of step down from serrated potion
- distance from base end to the circlip groove
- overall height of the ball joint

Alternatively, whether they have 334316 engraved on the base end
If the answer to that is yes then I'm sorted

Thanks
