Should the screws be English or metric?  This problem faced
the IEEE488 GPIB standard.  Hewlett Packard originally used
English and when the standard came out, sent out replacement
metric screws to all who requested them.

The IEEE 802.3 standard is very clear that the flange of the
15-pin D-connector is to be mounted on the outside of the 
case.  If, like Sun, you mount it on the inside of the case,
the slide lock mechanism is at the wrong height relative to
the connector flange to work with standard cables.  Sun
provides mating transciever cables that have the height of
the posts adjusted so that the connector mates properly.  So
much for plug compatibility :-)   On most transciever cables
there are two washers under the lock posts.  Both washers are
supposed to be there for standard cables.  You can get the
connectors to mate more snugly by removing one or both washers.

We find that we have to replace about two slide lock clips that
are bent beyond all hope.  We don't find that a major hassle.
A feature of the slide lock system that we really like is that
right angle hoods are available.  We use these on cables that
attach to wall plates so the cable can exit the wall and drop
down close to it.
