I must have gotten the good MSD6AL back around 1990. Still works fine.
I did think it went out on me once. Cooling the car at the track and got some water trapped around the magnetic pickup connection that was wrapped in electrical tape. I was using the points trigger. Anyhow, unwrapped the tape and dryed the mag pickup connection, and no more problems.
On The Charger, I had the box mounted on the inner fender in plain view so it would be easy to change the RPM limit pills.
On the Convertible, I mounted the CD box (Crane HI-6) under the battery tray.
I was thinking the same mi is from 89.
