K-member at the end of its life?

Seems we read of the LCA tube weld problems more in later cars (1973+). Probably another case of the factory trying to save money. Same deal for the torsion bar anchors, just a few spot welds in later cars. I would think the washer repair would work fine, since you are then welding to new unstressed metal on the K-frame, plus much more area at the washer OD.

You might want to re-angle the tube before re-weld, since best to move the lower ball joint forward for more caster. Of course, the LCA rubber bushing will flex to allow that, but better if aligned closer to where you want it. Some after-market strut rods are adjustable, allowing you to pull the end of the LCA forward. Most people use offset upper control arm bushings to move the top ball joint aftward.
