Replace "" column derived from SSIS characters

So I am receiving CSV files and for some reason they come as "123-45-9873".

Now I cut the "-" but the column is an SSN column, so I have "12345987 taking out the 3 and putting the" character on the table.

What replacement function can I use to replace the same character?

As a reference, this is what I am doing.

(DT_STR,9,1252)REPLACE(SSN,"-","")

and getting "12345678
