Locating sway-bar tabs

Not to step on anyones toes here, or come across as a know it all, but does anyone really think the guy that was welding tabs onto these LCA's actually had a measurement, needed for that job.
On 73-76 A bodies the tab is pretty much in the center of the LCA, and it's just eye balled where it would go.
The end links of the sway bar wouldn't even care at all if it was a bit different when everything is bolted up.

The guys on the welding assembly line were probably half drunk, and half stoned, all the time when they were doing these things back in the 60's, and 70's, anyway.
