Hello. I have a 1970 Mach 1 which I have owned for over 10 years. It was converted years ago to RHD before I purchased it. Age has crept up on me and I am looking to install power steering. The fact it was converted before I bought it, I am assuming the steering box and suspension bits etc where probably off a Falcon, but I don't know. My question to the knowledgeable is, would early Falcons, Fairlanes from say xw to xe era be the same steering boxes and suspension bits and be interchangeable? I'm hoping to just get the lot off a donor vehicle, pump, lines brackets and box etc. Thanks.
