Mine is well beyond 2 years old had it in my bug for at least 8 years or
so. I used to carry a set of points just in case, when they first came
out they were unreliable had my very first one go into total meltdown.

They work great until they die, and some people seem to have bad luck
with 
their dying within a year or 2. Otherwise, they are great, but many
owners have 
taken to carrying a complete spare distributor in the car, just in case.

I believe the Pertronix kit for the FI distributor may be discontinued.
That 
kit contained a specially modified rotor which was necessary to fit in
the more 
limited space of the FI distributor.

I prefer the Delta Mark 10 CDI (Capacitive Discharge Ignition) units.
They 
don't involve any additional parts inside the distributor and use the
same 
points, but they do have a box that you have to install somewhere. They
just 
wire into the coil wiring.

The biggest problem with points is rubbing blocks that wear quickly.
This 
happens when the dist cam isn't cleaned and greased at each tuneup. The
old 
grease collects grit which becomes grinding compound and roughens the
cam. The 
rough cam surface then rapidly wears the rubbing block.

One of the things I do when rebuilding a distributor is polish the cam.
This 
does wonderful things for point life. With a CDI ignition and a polished
cam, 
the points will go 10s of thousands of miles without attention.

I have Delta Mark 10s and Mark 10Bs available for sale if you're
interested, 
and a distributor rebuild only costs $50 plus shipping.

After ignoring my own distributor for over a decade, I just rebuilt it
this 
past summer. I knew it needed it, but I was REALLY surprised by how much

difference it made once the mech advance was completely free once again.
That car really came back to life after the rebuild.
