In the process of rebuilding my control arms I noticed this dimple in the driver's side lower arm. It's the size of a hammer head but I doubt that any human could swing a hammer hard enough to leave a mark this deep in metal.:) I don't have the car here to see if anything on the driver's side needs clearance but I don't remember anything there. The passenger side doesn't have the dimple at all.

I agree with Rick, if it were something for structural integrity you would think them all would have it. The other side of the car doesn't.

Just wondering, when you reinstall the lower a arms are you going to be using stock springs?
if so, what will be your method of compressing the coil spring and attaching the lower a arm?
just wondering, I'm planning on doing this job too.
Thanks
As was posted several times above, I was lucky enough to have a friend who owns a spring compressor which I used and it made the job easy.

Dimple was put there for the mounting of the front stabilizer bar. Early ones even had a hole in it. I believe this was the plan, and the
maker of the control arm made them that way. By the time the cars were getting made there was a change to the way the mounting
was made, by then the tooling was done, and there was no reason to remove it.
Do you think that since mine has one with and one without the dimple that the lower control arms were swapped at one time? The ball joints were still riveted into the uppers so I think those were originals.
