I am thinking about putting a header on my '70 FJ40. I also am going to be running the PTO winch. The header is going to be a Man-A-Fre 6 into 1 header. I dont know if the header will block the PTO shaft. Any help would be appreciated. Also does anyone know about that exhaust like hoiw it sounds. I am also doing the full exhuast from Man-A-Fre. I dont want it to sound like one of those stupid "rice burners" : lol. even though it is a TOYOTA!!!!
