i've been doing some research into doing a lowsteer conversion eventually on my truck. it seems that many people have successfully welded another passenger side arm upside down on top of the stock arm, and gussetted them heavily down the middle with some 1/2" plate or something. now, my question is, is this stuff safe to weld? i've heard conflicting reports that it's cast, and some say they're forged. i'm a good welder, but i'm a little worried about the material here, never welded cast steel before(if that turns out to be what it is)
