The plastic ball end on my boot lid gas strut has broken. The type sold by SGS are not the right shape, mine are a definite ball, those offered are square-ish. Any one know where I can get either some ball ends or gas struts with the correct ends. The ends on my struts are all plastic with a 6mm coarse thread, others on offer have brass inserts with 6mm fine threads. Please see attached photo, my gas strut is the one on the right Any help gratefully received
