They're not supposed to be vertical. Its like a cheap version of rising rate suspension.

or do you mean when viewed from the side, not vertical?

When viewed from the side, with the shocks unbolted from the top rockers the top of the shocks was not centred on the fixing into the rockers, they were approx 10mm rearwards, so shortening the rocker tubes and spacing them rearwards to improve the castor should allow them to sit vertical. It seemed that the top of the shocks were being pulled forward previously, can't of helped free movement of the shocks?

Yes it'll help.
The shocks with the rubber bushes are thicker than the ones with spherical bearings.
If i were to do it all again I'd have gone for the spherical bearing protech shocks and shimmed the shock in the chassis mounting to get them vertical.

As it is, I think i got about 5mm of play with the rubber bush type.

Fingers crossed for some dry weather over Christmas so maybe you can see if you've solved your issue?

Spherical bearings/Rose joints need high miss-alignment spacers machined to fit and centralise the shock in mounts.

Yes and no.

You could space with washers (small washers), as you are not looking for the spherical bearing to move the shock in that plane.
The reason for using them is that they are thinner overall at the connection.

Where they talk about the rod end body contacting the bracket in the video below. This isn't a issue for the suspension because it doesnt move in that plane

Most of the time, rod ends are not used correctly anyway.
But, I did use high misalignment washers for the rod ends on the front lower wishbones. Its a race item for fury sportscars with rod ends

Edit: (after a sleep) Basically we're not looking for articulation of the spherical bearings (in this case)

Someone agree with me

I certainly didn't (and wouldn't) use washers on a shock rose-joint.
