To start...






My rear lower arms are solid piece without a separate front/rear. I would really like to get rid of it and be able to adjust the toe and to some extent the camber.
So, question is.. is there a way to link 2 tubes, perhaps a double ended rod end, and if so, would it be strong enough for the roll bar?

 

Do you mean (what is commonly referred to as) a swaybar when you write "roll bar"? I think you'll have difficulties trying to use a spherical joint with the existing mounts. If you're willing to mount in single shear, it should be doable though.

In regards to the toe and camber, what piece are you calling the "lower rear arms"? The control arm, or the radius arm? To change camber, you're probably going to need to use "camber plates" at the top of the shock mounting.


5 is the radius arm (also called a radius rod). It's chassis mount should allow for toe adjustment.

If I didn't answer your question, you'll need to be a bit more clear, as I really don't understand the question as it is written.

 

Actually I'm happy just to get a reply, being the orphan of the forum and all .

The lower arm is the lower arm, #2. The radius I've already replaced with a heim setup. What I would like to do is take out the 3 point lower arm, and use 2 heim/tube set ups enabling independent adjustment of the front and rear half of the arm. As is, the radius changes the caster and toe together. As well as these bushings are no longer findable and it would give me some camber adjustment without making custom top mounts.
Basically, it takes care of many things at once.
My issue is the roll bar. It bolts to the lower arm and how do I do that with a heim/threaded tube set up? I found this..




but the biggest they have is 1/2-20. Which is too small to hold up. Now, my question is, has anyone seen any of those double ended heims bigger, or have other ideas how to do this?

Edit:... what about moving the bar mounting to the strut? Any way to do that?

 

My opinion, and only a quickly thought one at that, is that trying to replace the control arm with 2 separate pieces for adjustment purposes is asking for suspension binding.

There is no caster on a rear wheel, so I'm confused there.

Assuming my understanding of the suspension design is correct, arm 2 provides lateral positioning while arm 5 provides longitudinal positioning and toe control. If you want camber adjustment, a camber plate up top still sounds like the best solution to me.

If you want to move the swaybar mount off of the LCA, the first replacement I can think of would be the radius arm's mount. As far as converting to spherical bearings instead of bushings with the existing mounting locations, you'd want adapters like

on each end.

I'm using a similar adapter on my LCAs (yet another picture quickly stolen from Google image search)
