What's wrong with the coils? Cracked? If so you don't have to buy new ones. A lot of supra guys use 1" heat shrink and epoxy on the cracks. First you epoxy then heat shrink. I did this on my car because the spark was arcing to my cylinder head due to the cracks. All I did was head shrink the coil shaft and it fixed my problem.
