1964-1972 GM Truck LS Gauge Components

An LS in a 1964-1972 two wheel drive C10 or GMC pickup still has to feed the dash. For oil pressure, BRP lists an adapter fitting that takes a traditional gauge sensor. For rpm, its Tach Adapter works with a traditional tach or shift light on distributorless ignition.
