Untested Vintage Kelsey Hayes Hydraulic Brake Controller removed from an old truck I parted out. This item is untested.
I will ship quickly, but eBay sometimes states delivery in 3 to 4 days. eBay does not let me change that.
I cannot control the shipping company so please be patient if it takes longer. No returns or refunds. Thanks.
