Here is a pair of lower ignition wire suppport shields for your 56-57 Chevy with a V-8 motor. Mounts to the engine block behind the exhaust manifolds, these shields protect the ignition wires from damaging engine heat. Wires run through the rubber grommets, safely hidden behind the sheet metal shield. This shield is designed for use with the ignition wire supports. Fits all 1957 passenger cars and 1956 Corvettes as a correct reproduction, but it also fits 55-56 passenger cars as a good replacement. Don't let your pride and joy be without a pair of these beauties.
