Review by Wayne Carlile from , on 10/24/2019
This valve fit perfect with no need to bend the existing steel break lines or modify the support bracket. The threads were clean and cross threading wasn't an issue. The Bleeder tool did its job and prevented the valve from switching the emergency light on.
