MGB Air cleaner fitment

["Larry Hoy" <larryhoy@prodigy.net>]

I'm asking this question for a friend.  He has a rubber bumper MGB.  Recently 
he changed the ZS carb for twin SUs.  His car is
fitted with a power brake booster.  It seems that the clearance between the SUs 
and the brake booster is much to close for any
traditional air cleaner system.

What have any of you done to resolve this problem.

If you have pictures, or web addresses that would be helpful too.
