Pics Needed of Factory Sway Bar on 69 Dart
The original sway bar was a long skinny "limber timber" bar. Its forward mounts hang too low also. Most aftermarket bars attach to a 'L' bracket attached at lower shock bolt so neither factory attach clip location is used or req'd.
Unless this is a show car, I would buy a better aftermarket bar and sell that OEM bar. Someone will want it since even the limber bar is better than no bar at all.
