Well I have all the parts
MSD Window Switch, Zex system with TPS switch, and a MDS DIS-4 Plus which will allow me to easily adjust timing in addition to providing few other protection features. Now I just need the time to install
I was able to get the DIS-4 cheap as it was a display model, the system uses part 8870 to sit between the coil housing and coils to control timing.
