Re: ignition swap ??
Newer is not always better and in some instances worse. So, don't swap just because you want a "better" ignition. In fact both ignitions are the same. While I am not up on nthe years, the 89 will have ignition connections made on a terminal board while the 87 MIGHT have quick-connect electricals. Personally, I prefer the quick-connect version.
If you are handy at splicing wires, you can convert either system to be compatible with the other's components.
