If I need to replace them for some reason I can just unscrew the shunt from the firewall.
My solution is that at next service, I will put the sense wires on the same terminal as the bus wires. But the sense wire terminals must be on the bottom next to the brass blocks. There will be a slight error in the reading because of the extra contact resistance and the main current flow, but I can either calibrate that out, or not worry about it; I am not using the shunt current for any math so if i am off by 10%, I dont care.
