So I noticed something odd about these LCAs...

So I obtained a set of '73-'76 LCAs with swaybar tabs. I noticed that the swaybar tabs are only welded to the LCA on one side of each vertical. Is this how they always did it? Since I'm going to be welding on the reinforcement plates I thought about welding the other side of the verticals as well. Has anyone else seen this?
I just looked at mine. They are welded on both sides. Hope this helps.
