Well, the overall shape is the same, but mine don't have the button in the middle.
Another thing, looks like you plugged one of the ports on the proportioning valve that could go to a front wheel, I don't think this is a problem, or is it? Do you have a T fitting at the left front that then feeds the right front? The trucks I have put together with the similar looking but different proportioning valve I have run two separate lines from the valve to the front wheels.
Also, did you use Teflon tape on that plug? I thought it was inverted flare, and needed no sealant, or is it 1/8" pipe?
Do you have rear disc or drums? And if you have drums did you use a 1/4" line going to the rear axle? Just a guess, but if you have 3/16" going to drums it could create enough of a restriction to cause the proportioning valve to act funny?
