Reply to "Spreader Bar - Camber Bar - Square Steel"

No- the oversized holes in the fenderwell tabs will allow the bolts to move, unless the straight bar is firmly jammed into the backside of the provided holes. You cannot tighten the bolts tight enough to keep this from happening- even gr-8 bolts will break first. I make little aluminum captive filler pieces of scrap aluminum to fill the remaining area of both sides of the holes and prevent the bolts from moving in either direction under cornering stress.

Incidently, the very same thing happens with the oversized slotted holes in the upper front a-arms that retain the upper balljoint carriers for camber adjustments. They can also be prevented from moving once adjusted, with the same type of captive filler pieces in the oversized a-arm holes. No need for complicated camber-locks, just some filing on pieces of 3/16" thick scrap aluminum.
