NOS Delco 4x10 front dash 10 ohm speaker, part # 1222661; group # 9.650. This speaker will fit in a 70-72 Skylark/GS/GSX but the factory "fork" bracket will need to be modified to fit the direction of the rectangle magnet for mounting (this speaker/magnet is configured for a different mounting bracket that is turned 90* from the bracket in the 70-72 Buick A body). Please research the part number and pics to make sure you understand what you are purchasing. $50 plus shipping/tracking/insurance from Texas.
