Oracle does not support communication via db links between version 9 and any version below 8. You might try placing db links and synonyms to and from the two non-compatible systems on a version of Oracle that both of the others can communicate with, that is, 9 -> 8 -> 7.3 where -> represents a remote synonym and link to the database version to the right. There are limitations to this approach such as the objects in question should be simple tables consisting of common data types like varchar2, number, and date etc....
