It just dawned on me that the only thing I probably had to do was to sand the paint of the back where it touched the wire. The strings will most likely pull ground from the string through holes where I will put the strings into the bridge. Oh well, the extra bit that I sanded paint off from won't hurt, and will be under the strings anyway. And I'm sure over time it would have worn away paint anyway.

Just wanted to update in case anybody else neglects to see the obvious like I did tonight. It's late, time for bed.
