Shock mount diameter

[williams2]

Hi
i'm after the size of the end of a shock absorber on the rear of a Roadster(lower mount), I'm thinking about fitting a rose joint to the top of the upper book spec rear wishbone rather than the bush, the reason is because I want to fit rose bearings on the lower wishbones inboard so I can adjust the toe angle, i think there is just over 42mm from the rear upright upper wishbone camber mount to the shock mount, the standard camber diameter is 33.7mm tube, the rose bearing will be larger, just want to know how big it could be without clashing.

If you could let me know the shock manufacturer the size is also please.

Any information appreciated.
Cheers
Lee
