The coils (and presumably ICMs) are the same in a wide variety of applications. For example, my dad'* 2001 Regal is showing symptoms that may be related to ignition coils (hard starting during damp weather only). If I can't fix the problem by putting some di-electric grease on the wire connections, I am planning to put the coils from my 93 Bonneville on and see if it works. I checked on the acdelco website, and both cars use the same coils.
Chilton'* calls for measuring the resistance on the coils to test them.
