@jonjebus: Before we install the control valve assembly onto this 1967 International 2504 industrial tractor, we'll need to do some prep work. First, we'll try to unstick the fitting on the hydraulic supply line. Then, we'll clean up and paint the mounting bracket for the hydraulic control valves. While that dries we'll go to NAPA Auto Parts to pick up four new hydraulic hoses and we'll have them install swivel fittings on the ends. That way they'll be easier to remove if for some reason we need to do so in the future. Lastly we'll paint the control levers of the control valves to make 'em look nice and new.
