Boxing Control Arms

[leestanger]

I am in the process of going through my 65 2+2 suspension. I am doing a lot of the suspension upgrades (negative camber kit, monte carlo bar, export brace, konis, suframe connectors, urethane bushings etc.) and am wondering if anybody can give any info on boxing the control arms. I understand that the old Trans Am racers did this. For a street car I am not sure that coughing up the ante for the tubular jobs makes sense and the boxed ones (although they do have bearings instead of bushings) from the aftermarket are about $300 a pair also. The whole idea seems pretty straight forward in terms of welding a layer of metal across the open "U" in the stamped pieces (but not covering the bolt holes where I can't get a wrench on them). Seems like a way to add a bunch of strength (if my sense of geometry and structural strength is close to right)for a few bucks and some spark time with the welder. But I have fooled myself before so I wanted to ask those who might have some experience. If someone knows of links with pictures that I can use as a guide or whatever else can give me a better idea of what is best I would appreciate it.
