Camber adjustment crossmember repair

This type of repair, and yes I have done a bit of it too, is not unrealistic on a car that is as old as these are now and was not manufactured with the idea that 45 or so years later people would be working on them trying to get them to adjust.
Most AMC cars became beaters rather quickly and were driven as far as they could go with out making any repairs at all.
I have owned a number of the post '70 cars and rebuilt the front end on even more of them and it is amazing how well they drove considering most of the front end was shot completely with these things bad, the lower control arm woggeled out so far that the bushing was no longer able to be pressed in, it just fell through, upper control arm bushing metal on metal, the rubber gone and strut rod bushing missing great chunks of rubber. 
And the cost of repair far greater than any value of the thing as transportation was worth.
They would clunk pulling into the driveway and try to change lanes when the crack in the concrete was hit on freeways. 
The have in my opinion a terrible front end, but it works pretty fair with new parts in them for quite a while.
But in reality, all they had to do when built was last through the warranty period with out causing a call back.  And that they did.

Just thought it might be easier to resurrect this thread rather that begin a new one.

My opinion.

The eccentric isn't a very reliable alignment method no matter what is done to it.

My question.

Does anyone have any good ideas to eliminate the eccentric altogether?
I mean other than the multiple holes in a square of flat stock.

Maybe remove the bushing and weld a female threaded boss to the end of the bottom control arm and attach a Heim joint. Then weld in thickener plates where the tab plates are and use a through bolt and lock nut? Street use might hammer that to bits in no time though.
