I've never seen any that rest against the retainer wire, left or right. There has to be a little tolerance or forgiveness there for play in the K-member bolt holes if nothing else.
Only once when a shop we call exesstire[express tire] did front suspension in a dart and instead of unloading & removing the bars & lower arms then inserting the the bar in the L arm [completely] they just assembled the lower & strut rod then hammered the bars into the lower arms which resulted in what you are talking about along with a refund and signed waiver of no lawsuit.
It also took them 4 days, when it takes me 1hr a side while sipping on a beer can.
