i have an old napa book that has a pic of a dash lamp identical to the halftrack style. when i put that number in the napaonline site it looks a little different with the mounting flange. maybe its good for parts to get yours going or maybe the online pic is wrong. anyways let me know what you think if you buy one.
Part Number ECH DL6190
