I suppose if there is a sender made that fits your No-Limit tank which also has the same resistance as your 60 gauge then you are in business. My experience thus far is that senders are made for specific tanks and gauges. I think finding a sending unit that fits that particular tank and provides the correct resistance for a 60 gauge is unlikely. You will probably have to either use whatever sending unit is made for that tank and then cobble together an inline resistor or series of resistors to get the sender to work with your stock gauge or custom install a sending unit for a 60 (if it can be done).
As far as the fuel sender resistance goes for the 60 gauge it is my understanding that Ford applications prior to 1987 operated on 6 Volts and should read 10 Ohms empty and 73 Ohms full...
