Ok I have a 89 TBI I am having some spark issues with. I am going to Autozone today to get it scanned. I have a 78 with HEI that I know everything works on. My question is My 89 has a remote coil the 78 has the "in cap" coil. Can these be mixed and matched? What is interchangeable? I would rather have the "in cap" setup on my 89 as far as heat and stuff I don't like the remote coil. The 78 is a parts truck so if I can use parts instead of buying them this would be great /forums/images/graemlins/thumb.gif Thanks everybody.
