300tdi air box & door alignment - any ideas?

Hi

can anyone help?

the airbox on my defender is loose and rattles and does not seal the filter properly.

do you know where i can get a new air box, and mountings [the rubber ones which bolt to the air box.

i have searched several parts sites and cannot find one anywhere

also can you advise on how i can re-aign the door hinges. my o/s door needs to be 'pulled in' to the door frame and rubbers to stop wind noise at speed. the n/s door is fine and fits like a glove, well almost!!

thanks
