The Accessory Installation manual and the tech sheets, found in the NOS Yankee 77 clearance light box, indicate a 3-cluster & 5-cluster configuration & layout dimensions for installation. We have removed a few roof caps, in favor of a roof cap with no cab clearance lights & saved them, for use as a template, when installing cab clearance lights.
