Concern With R4R or RR4R Chassis After Recall Repair?

We had our trailing arms replaced 6 years ago (after one broke) and have no issues since then. The replacements were from Source Engineering and are several times heftier than the originals. I think as long as replacements were like ours there should never be a future problem. I have read of replacements being new ones but just the same design as the original failed ones. Also some folks welded braces etc. and rewelded the cracked ones. I would stay away from those "repairs".
