The pirate jack kit is just a 73+ Mopar disk set up. It’s all remanufactured Mopar parts.
The 73+ disks will fit a 67-72 car, and they should work with the 67-72 sway bar as well as long as the calipers are put the the back instead of the front. You shouldn’t have to abandon the factory sway bar for that kit to work.
It’s difficult to tell from the picture, but the welds on the LCA at the sway bar tab do not appear factory. So it could be that the tabs were added and aren’t in the same spot as the factory tabs. Or maybe the tab on that side was damaged and repaired at some point.
To the OP, is there interference on both sides? Or just one? Can you post a picture of just the sway bar tab and the weld?
