Point of attention for the owners of one MG MGB, but also MGA, T en Y type, Midget, Austin-Healey Sprite, 100/4, 100/6, 3000 and all the other classics of the same suspension system use. The spring dish of the front suspension can rust through in common without you actually noticing.
With an age of at least 35 years, that is not so surprising ... Water, mud and brine remains in the dish, moreover, everything is 'scoured' by the mounted ones coil spring that moves actively during every ride. Also in the dish. If such a feather sinks through the dish, then you have a serious problem. So just inspect? Prevention is still better than cure.
