I bought a 1983 CJ7, about 18 months ago. I have read all I can find about the ignition upgrades. All of the ones I have read state the upgrade is for engines from 1978 to 1990. For what I can find out, I have a 1983 CJ7 with a 1977 engine in it. Why...I have no idea why it has this engine in it. My question is, will say the Team Rush ignition upgrade work on my engine. I think it should. Thanks for your help!
