Also cheap and effective - Irish Spring soap bars. They smell nice, and have such a strong scent that it drives the mice away. I use that trick in my sheds as well as in cars. In the cars, I hide the bars under the seats and in the dash. My dad has used then in the fender wells of his truck, since the mice like the taste of headlight wires. I bought a bulk box of soap at Costco, and still have over half of the bars left. I guess I'll never have to worry about not having soap for the shower, if I run out of the usual stuff.
Door hinges can be repaired with just the bushings if the hole isnt egg shaped from the bushing being long gone. Pins might be available at the local auto parts place, just not listed as for an Eagle. You can try to match up a replacement. One final thing I've come up against is excessively worn door check springs - the rollers get seized up, then they wear a groove in the spring. When that happens, its time for a hinge replacement.
