I used left and right hand threaded  rod ends so a simple
twist of the brass rod adjust the timing over a
wide range.

The other thing I did is pilot the trigger
mechanism  on the internal bore of the e-shaft pulley. Just so
happens this is 2.75 inches ID so 2.75" OD 1/8 inch
wall aluminum  tubing worked perfectly. The run out
is less than a .001".

The 1/4 inch plate rod end bracket uses the bolts that normally
holds the apex oil seal metering device. Nobody runs this
in aircraft or race car so they are convenient and available.
People mix 2 cycle oil with the fuel.

We are scheduled to test the complete Lamar Instruments
ignition system at the Sebring race in Florida on the 19th
of Julyin an E Production RX7SCCA road racer.

Show up Lynn Hannover :)
