ol' Skool Triple Louvered Ballast Resistor Cover. I found these in batch of parts from a Chevy parts house that went out of business. Cool period correct part to dress up your hot rod.
This is a made in the USA polished stainless steel ballast resistor cover that will cover up the ugly ballast resistor on the firewall on 1955-1964 Chevy Cars and Trucks.
This cover will only fit over AC-Delco resistors with the wires that insert from the side
