A Ford Parts counter would probably be your best bet for the cable and thermostat housing. You could try the SN Classifieds, but I doubt small items like that are going to be very plentiful. The same goes for the radiator hose. There are plenty of aftermarket "braided" stainless steel hoses on the market if that's what you're referring to?
ok thats what i figured i just know ford parts counters will cost a ton. What should I look for in a braided hose? I am doing a mark VIII swap so dont know the exact length and such just that it goes down to the thermostat housing.
