How I added A Vacuum Advance Limiter to Mopar Electronic Distributor

Here's how I added a limiter to the vacuum advance on my small block Mopar Electronic Distributor. I started by marking an "X" where I drilled a 9/64" hole and then tapped that hole with 10-24 threads to accept the machine screw and locking nut. Now I can screw it in out out to adjust how much advance timing the vacuum canister can pull. It's nothing new but thought I'd share a quick video of how I did it.
