Rubber bearing on the air filter box

servus, I’m a little desperate. the air filter box in the engine room is fixed with two screws that each has a rubber bearing (I guess times). the two rubber bearings are both so through that the air filter box is quite rattled, and that is annoying. I was at the FFH and wanted two new rubber bearings. “No problem, I order them and report me.” a week later I wanted to pick up the one. and what did he order? two sockets from the air filter box to the motor g ehn….okay, once again showed him what I really need. ok, he has to clarify with ford in hell. two weeks later the info: is not available individually. only a completely new air filter box is sold for expensive money. so my question: does someone know where I get the two rubber buffers from? or should I look around for a good used air filter box? whereby the probability is great, that they are already brittle. am grateful for helpful tips oh yes, is e in RU8 petrol
