The longer pins should line up with the deeper holes in the key, shorter for shallower, I think there are three lengths, pins could either be harvested from a scrap lock or machined on a lathe, a small lathe! looks like there should be six caps, springs and pins, missing a few bits,

Pat, don't forget that the Petra key has divots on both sides ... so that could mean 12 of each. but i don't know that for a fact, it might just be one sided so you can put the key in the cylinder in either direction and have it work. Dick can you take a detailed pic of the inside of the barrel an both sides of the cylinder.

i would suspect that the pins probably work from other types of locks - Dick, if you put a caliper on the diameter i can verify that.

I counted today. I have 6 springs, 4 long pins, 2 short pins, and two little cups...maybe what you are calling caps? If so, I'm missing 4. I'll look more.

Are you calling this the barrel or the cylinder?

At least yours lasted a really long time. Mine came apart like that back in 1982. I recall using a screwdriver to start the car. I'm of no help just blathering on here. I lived near Korman Autoworks at the time and took it there; it was a rather involved repair to replace it all from what I recall. I ended up with a 2nd key just for the ignition.

Thanks. Misery loves company. ;)

Something is hanging up in the lock cylinder, there is a large pin that drops onto the column when key is in off position, I don’t think e3 or e9 are any different, they use the same lock cylinder.
Chris,
You were right. I fooled with it some more today. The lock does drop in with the key still in the cylinder. It must have been a little sticky and by removing the key it was able to release and drop in. Works like you posted now.

Scott,
I'm unable to get a good picture of the inside of the barrel. The one I posted in the first post is as good as I can do.

Here are pictures of both sides of the cylinder...

Lousy pictures but you can see 4 holes on one side and 3 on the other.

Here is the bottom end of the cylinder...

I did find one more cup, so the count now is 6 springs, 4 long pins, 2 short pins (or one medium and one short....hard to tell), and 3 cups.

Mine fell apart 20 years ago and I was able to replace it without much trouble - assuming a new one is even available today.

Might just be less trouble to install a push button start mechanism:
