this control arm that people are selling to replace rod ends&bushings,do you guys think they are worthy of a street car for daily use or should i stick to my ssm uppers?they offer all sorts of degrees of rotation,so the rear end may not be in bind with these?they are good on paper compared to what i'm running now,but i'm intrested to hear what you big hitters on this board have to say,you've always steered me in the right direction before.its rather confusing because i've read before that Spherical Rear Upper Control Arm Bearings aren't good in the rear end housing for street use,these look similar. ](*,)does the fact that vic edelbrock offers a version with these bushings mean anything?their stuff strikes me as street proned.
