OK, I've used the search function, and as far as I can tell, have followed the directions. Can't get the cylinder to come out. Using a paper clip in the small hole, and the ignition key, tried turning forward, backward, starting from the acc position, everything. The key just slides out of the lock when when I pull back on it with the paper clip in there after turning the key. What am I missing here? BTW, it's a 1970 GMC. Thanks!
