What SWAY BAR to choose

I’m not an expert but I believe that complicates things since you appear to have 73-76 lcas with the tabs in place for the 73-76 bars as well as front mount calipers.

Hotchkis sells a bar that mounts to the early k-frame and uses the later LCA mount. Perfect for this situation. But the OP started another thread about that situation and said he thought he was going to use that bar but now he is asking about Hellwig bars. So either he can’t get the Hotchkis bar, he doesn’t like the price or he has some other reason to swap LCA’s and stick with the earlier setup.
