This is an NOS 12V coil mounting bracket, Ford part # B6A 12043-A.  This bracket was used on V8 Fords, Thunderbirds and Mercurys starting in 1956 when Ford changed to a 12V electrical system.  Later replacement coil brackets have an open mounting hole on the one end. This bracket was never installed and has the Ford part tag on the front loop.  We charge actual shipping or your welcome to pick it up.  Thanks!\
