Correct, very different from the 67-72 tab location. Next to a 73+ tabbed arm they’re nearly identical.
On my Duster I went from a factory 73+ tabbed LCA to the QA1’s. I shortened the end link slightly for the QA1 LCS’s, but that was the only change I made for the 73+ Hellwig bar I run. The tab on the QA1 is a little different in the vertical plane, but the end link was still nicely aligned. Just needed to be a smidge shorter.
