That would depend solely on what the mice ate. If you look at the
wiring diagrams in the tech section, pick 81-87 and what part of the wiring diagram you want to look at, you can see in the V8 engine diagram top left portion is your starter.
You might want to familiarize yourself with these if you haven't already.
The battery terminal on the starter. You will also see
2 fusible links that are tied in there that run into your key switch and basically back to your starter. ( it is a little more detailed than that, but you could follow the circuit if you want).
So if you jumped the battery terminal of the starter solenoid to the other pole on the solenoid you could spin the starter, but I am not sure how much damage there is to the wires or how many the mice got to.
I know you just want to get it to turn over, but in the process you might do more damage if the mice say caused a direct short. You could end up blowing your fuse able links, or damage your module or worse.
I am sure someone will tell you how to bypass all the wiring (if possible) just so you can start the engine. I personally do not bypass things too much, because in my line of work, the systems are there for safety and well people could die if they bypassed them, so I have learned and lived most of my adult life to fix rather than bypass. So I will not be a good source to tell you how to do that.
