I recently finished replacing all the hard lines, hoses, wheel cylinders, calipers, prop valve, and master cylinder in my '86... And as murphy's law would have it I need one fitting to get everything together.
Does anyone know what size/type the fitting is that connects the rear master cylinder reservoir line to the proportioning valve? And why is it necessary to have 4 different sized fittings on that stupid valve if its all the same size line??
