Basically something like the first design there is good I think the one I have at work is made be Thexton.

Also have you checked to make sure the dist. shaft is still turning? I'd pull the cap off and have someone crank it and watch to make sure it's spinning like it should. We've seen some strange failures on dist. drive gears lately.

I keep looking at the pickup coild going "it's the only thing I haven't changed" - but it keeps testing good. I found a new test on the internet that isn't in the FSM - it says during cranking, the pickup coil should see at least 3 volts, I believe. Lower than that and it's bad. I'm gonna try that. AFAIK the shaft is still turning because the rotor has been in different positions when I've pulled the cap each time....ugh. I'll get the spark tester and take the ICM to autozone later.
