as the second one it looks like the bush is dead.
like i said the bolt goes through until the shoulder seat on the rear subframe leg. it can not go any further.
so fit without the arm or bushes then you then know just how far it does go in.

That pin looks like it has been bashed to hell.

If I fit the pin without the bushes it sits further in by a few mm. But I've tried for hours and I can't get the pin to go in that far with the bushes installed.
I'll measure the length of the thread poking out with no arm installed (when the shoulder is flush with the subframe) and compare it to when the arm and bushes are installed. They should be the same obviously. The bushes are a hard compound and don't compress much so I'm not sure it's possible for the shoulder to still sit flush.

Have you tried sliding the bush over the pin off the car? Does it seat properly?
When I removed mine, there was corrosion on the part of the pin where the bush seats, it needed some clean up before a new bush would seat fully.
Also, is there a nut on the rear of the pin?

Along with Deathrow's suggestions, dry fit the pin on it's own in to the Subframe, you'll get a better picture as to how it should sit too.

And yes there's a nut and a spring washer installed. I only see one thread exposed after the nut. I saw 3 with the old bushings but the bushings were destroyed so the pin was able to go deeper through the subframe mount.

On old parts, worn out or corroded, even slightly the lower pins need a bit of jimmying to get them seated properly. That said, they're 30 quid each from what I remember likely would be better off with some seeing to.
All in all, take some (very) light abrasive to them and twiggle them about when seating them. They'll go in proper.

That is how they are, even the original sleeved rubber bushes should be like that. The idea being when done up, the inner sleeves of the bushes are pinched tight.

Is it the upper or lower ball joint you're trying to tighten?
If the upper, put a trolley jack under the lower ball joint and out some upward pressure on the joint, that should seat the taper enough that you can tighten the nut.
If the lower, put the jack under the arm itself and raise the jack just enough to again seat the taper in the arm, then you should be able to tighten it OK. It shouldn't, but don't bend the control arm!
