The Allis-Chalmers "D" series Tractors that were equipped with front mounted Headlights, had under the hood a junction block for the two seperate Headlights. Over the years, being they were located under the hood over the engine,  engine heat and Mother Nature, would eventually dry rot the junction block and the block would break into piece or hang from the Headlight circuits. Here at B&B we offer a new under hood Headlight junction kit. Comes with junction block and new spade connectors.
