as you can see in the pic,the weld broke,,was probably a cold weld,, i have knowledge of the building of these upper A arms,, but it is not for me to tell,,i met the maker before he started advertising these,,,
i have tublar upper A arms in my barracuda,,for almost 10 years, no problems,,but they are welded properly,,,and do not use street rod 4 bar ends,, when i seen those in real fro the first time,,with adjustable 4 bar street rod ends,,i was glad i had the type upper A arms that i have,,
many cars street rods etc have tublar upper A arms,,with no problems,,they are built by people that have knowledge of different metals and there strengths,,before and after welded on,,
i hope the people in that car are ok,,,and that he can fin dthe parts to fix it ,,
