A friend of mine gave me lower control arms and a rear sway bar for my 69 SS. I’ve never installed one before. I know these bars come with shims but I’m not sure how they get installed. Do they take up the slack between the sway bar and the control arm or is there more to it?

Thanks,
Bubba

Bubba,
For what its worth, I installed boxed arms from another car, and an aftermarket swaybar, and I didn't need any shims.
I think the shims are just to adjust fit, but doubt you'll need em.

Are you referring to the ~1/8" thick backing plates that go inside the arms? If so, they are not shims but are intended to reinforce the arms where the swaybar bolts on. I believe they are illustrated in the factory assembly manual.

Most of the aftermarket companies sell sway bar kits which include shims. I'm not sure how thick they are. My concern is that I have only the two lower control arms and the sway bar, no shims. Didn't know if this would be a problem. I'm also missing the bolts that connect the sway bar to the control arms. Do these bolts need to be graded or can I visit the local hardware store?

Thanks,
Bubba

I would definately use hardened bolts, and not cheap hardware store ones. You won't really know if you need the shims until you put the bar on. If there is a sizeable gap between the bar and the control arms, then you'll have to use shims. I think the point is, you aren't supposed to stretch the bar into place with the bolts.

Be sure the control arms are reinforced so you don't crush them with the bolts.
Use high strength bolts like grade 8 - the local hardware or Lowes store may have them.
Use locknuts or good locktite so the nuts don't come loose.
The shims are for taking up space between the anti-sway bar and the control arm - you will cause a bind and excessive wear if you pull them together (more than a VERY small amount like 1/16-1/8)with the bolts.
Mine did not need shims.
You can make shims from sheetmetal if you don't have any - nothing special about them.
Just make the total thickness to fill the gap snugly.
