K&N cold air intake trouble

Question: I tore the rubber receiving mount that threads into the truck and receives the airbox mounting bolt. can I use an adhesive to fix it? or do I need to order a new one? Also, it seems the included washers are too small. My drill was too powerful and I ripped the sh!t out of the housing. Anyone else have this issue? Also, the threads are corroded. that receive the rubber hardware, should I just get a head tapper and recut them?
thanks for the help-
Alex

 

Pic? I think I may know what you're talking about. If it's something like what I'm thinking, you may be able to find something that would work similarly at a good hardware store.
