1970 Duster

Hi everybody, I am building a 1970 Duster. I have pictures under member restorations. I have a full Cap Auto Products assembly under the front KFrame, UC Arms, LC Arms & Strut Bars. 2 people have warned me to take that stuff off due breakage from poor welds(upper control arms). I am very concerned about this. Has anybody else had a problem with these parts. If so please email me. Thanks Steve
