Lower Control Arms

Without tabs they are all the same. The tabs can be welded on your LCA's. 72 back is a wider sway bar so the tabs are near the end of the LCA. 73 up the sway bar is narrower so the tabs are a lot further in. I think the 73 up sway bar may go through the k frame from what I have read but you will need to check that out for yourself to make sure. There is always an aftermarket sway bar option too.
