I recently bought a new lock set for my van, inclusive of a new ignition barrel.
I attempted the removal of the old barrel yesterday, starting by removing the steering wheel, then undoing the allen bolt which secures the ignition housing from the steering colum. I then pulled the ignition housing from the steering colum, and that's as far as I got

I just cant figure out how the ignition barrel itself is removed from the housing.
It would be great if somebody can help, as I can eventually have one key that works all locks, and of course, this pesky igntion grrrrrrr.
Any advice very much appreciated

Mark
