rywegh, their LCA’s are stamped steel from that company and are for the Cobalt car which has different dimensions then the HHR. Moog RK620897 and RK62898 or AC Delco 45D2486 and 45D2487 or GM 15787555 and 15785556 LCA’s are aluminium as it came from the factory . I’ve installed all three of these brands and had no issues with them. I have replaced those stamped steel parts they fit, but aren’t quite right and they throw the alignment off.
