coil

one of the coils in my 88 gtu is going bad, at least i think it is, because my car is missing quite a bit and it is only 1 rotar that is missing. so i want to replace the coils with something that has a little more power/spark whatever. i was going to use msd blaster 2 but then i realized that they only have 1 terminal and are designed to work with a distributor or whatever so what are my alternative choices. any info will help. thanks
