Hello, I am new to the sight, and new to Mopars. I recently bought a 1971 Roadrunner, rm23n. I have been reading up on the differences between 71 satellites and roadrunners, and one major difference I read about was that Roadrunner's have brackets welded to the lower control arms to hold the stock front sway bar. Satellite's do not have front sway bars and do not have these brackets. Now, my roadrunner doesn't have a sway bar, and I cannot tell if it has just been removed, or, if my lower control arms are actually satellite lower control arms. Can anybody tell from these pictures if my lower control arms are from a roadrunner or a satellite?

Welcome aboard, and yes...those are sway bar tabs on your arms.

that is good news! Next question, are my lower control arms exclusive to the roadrunner or did they come from the factory on satellites too like the ssp?

That's a sway bar control arm and the K-frame sway bar bracket is visible as well. The bar and end links are missing, pretty easy to find replacements. Although most Satellites didn't have front sway bars, some did, would have been the same components standard on the Road Runner.
