Question about hood closure with different carb and manifold

[JanS]

The back of my hood is shimmed up a bit since the clearance has changed with the new manifold and carb. setup. It isn't much but I'd like to have the hood flush and to be able to use the rubber air cleaner gasket again for the cowl induction hood. Does anyone make a drop base cleaner bottom to use with the rest of the cleaner parts? Thanks!
