Need ignition modules for '82 mondial 8

After placing and replacing the new battery several times because I had no juice in the car and checking it, but finding it was fine, I replaced it again and this time accidentally reversed the positive and negative cables. When I turned the negative disconnect back on, I blew the switch and must have blown the rest of the ignition kmodules as well. What a dummy! Well, in my defense, I am disabled and could not get down low enough in the wheel well to see which cable was which. Obviously, I should have paid someone to do the job, because now I have a dead as a door nail Mondial!
Anybody know where I can get some modules cheap?
