you can use a crystal command as your source (replacing for the table that has the dashes in the SSN).
When you go to add a table via the databse expert there is an Add Command option usually above the DB name. Double click it and it will open a screen to write your command.
When writing the command you can use a replace function to strip out the dashes.
Example:
select *, REPLACE(SSN, '-', '') AS SSN_2
from tablename
Now you can add the second table (the one without the dashes already) and join the table and command together on table.SSN = command.SSN_2
