How do u replace an ignition Barrel on a 59?

[59 DIRTY RAT]

Hi Guys,
I bought a whole set of matching key/barrels for the 59, the doors/trunk were straight forward but how do u change out the barrel in the ignition. The electrical part is off the back and there looks like some type of retaining clip inside the barrel?
Anyone done this before? I tried searching on this site for a thread but couldn't find any, I thought it would be a fairly common swap? Is there a diagram or step by step instructions anywhere?
My caddy when I bought it only came with 1 ignition, 1 trunk and 1 glove compartment keys all different and no door keys!

Thanks Guys, Andy

There is a small hole in the bezel next to where the key enters the lock.   Straighten a paper clip and push it in the hole, and with the key in the lock, I think you have to turn the key either to the left or the right, one click.   Then push the pin in further, and if it is in the right place, you will feel a spring being pushed in.   Push it in about 3/16" and at the same time rotate the lock to the right, as if you are turning the ignition on, and this action will release the barrel.

The installation is in reverse, but you don't have to use the pin.

Don't forget to disconnect the battery, as removing the tumbler will turn the ignition on.
