i have a factory 1050 FBS from a explorer II. A dog ear is broken, and the insulation is splitting on the black outer sheathing not the internal wires also have about a 4-inch Excelerator E coil with lower rod, insulation has crumbled on that one and one leg of wire is exposed in about a half inch spot 25 for the pair plus whatever it cost to send them. the smaller coil was barely used but the 10 inch was well used. pics on request send a pm and i'll get you somePrefer factory 10" but others considered . TIA.
