They’re stock equivalent on all counts bar the steel inserts for the ball joints.
Most wrecker parts won’t have the ball joints included so neither the steel cones.
Generally these may or not be supplied, if you have pics they’re black and can be seen on a top view.
Its a ally looking cone hole w/o.
Around $70 or more a pair at the dealership parts counter, but check for stock or order prior.
Its the same part as found on GR etc STi ally control arms, I’m fairly sure as procuring a set was not a drama, locally.
