Fuel Gauge Ohms

Since I had to take my gas tank out to weld up my rollcage, I went ahead and threw in a new sending unit, hoping to get my gas gauge to work. The stock gauge doesn't work and I'm just going to put an aftermarket gauge into the dash. With that said, I need to know what gauge to order.

At what ohm level should the tank be full or empty? I'm thinking that it should be 73 empty and 10 full, but I don't have a FSM to make sure. Could anybody help me with this? Thanks

 

It should be 73 - 10. The link below has all the ranges for a '65, but I have found they are the same for the AMC's.
