try mick at japline wreckers in malaga for standard headlights, i'm sure bram will help you swap them over if you want to sell him your current ones

sounds like your mechanic is taking you for a ride, any decent mechanic would normally try to source a good condition secondhand one from a wreckers because we all know subaru charge crack pipe prices for this sort of thing

south of the river i'd recommend chatting to doug at s-technic, north of the river i would be talking to jim hall at bluestar

both great subaru specialist mechanics
