Upper control arm tech help

Hey guys,
Need some advice/help in upper control arms. The "bracket" that adjusts caster/camber that the eccentric bolts push against are weak/breaking, we have thought about going adjustable tubular anyways and was wondering if the adjustable heim style or the PST style adjustable uppers will do away with the eccentric bolts and all the caster/camber adjustment is in the heims/sleeves. Is this thinking correct? Thanks in advanced!
