need a fix for controll arm aligment tabs

Check the condition of the actual frame rail.

I just got thru replacing the upper frame rail/control arm tabs in a 67 Barracuda that had been condemned.
Wouldn't hold an alignment after owner spent $7k having suspension done, and other stuff.
Upper control arms were moving afict .
Dirt collects and forms mud in the pockets between tabs, top of frame rots
