ok - this post just makes me mad --- mad at myself, because I have tried for quite a long time (months), to get that stupid ignition cylinder out. i have searched all the possible postings for it (in the past). and truthfully, i don't understand what i am doing wrong.
here is a pic of my cyl:
if you look, you can even see the little spring that you should push with the allen wrench inside the little hole. but here is my problem --- the spring is only visible when the key is NOT in the accessory position. if i turn the key to the accessory position (clockwise), the hole ends up at about 5 o'clock. (Not 12 o'clock). So, I have tried many combinations. Allen wrench before turning the key. Allen wrench after turning the key.
Bottomline, the whole cylinder assy is getting really worn out, and I am just about at wits end. Any more suggestions? Is there a difference in the cylinders from 68 to 72? Is the hole in my cylinder on the wrong side? Is this the wrong cylinder for our trucks?
grrrr.

jewels.
