Removing a seat post spacer I am trying to get an old Raleigh SC 40 bike back to riding condition. The seat post doesn't tighten at all and the culprit is that the spacer sleeve is stuck well into the frame. 

In order to get a new seat post, I would assume that this spacer needs to be removed.  Any ideas for easy removal.  I tried to wedge a small flat screwdriver between the spacer and the frame but still can't loosen it. Looking at it I would assume that it is aluminum (definitely metal). Use WD 40? Then what!?! Thanks!
It’s much easier to push than it is to pull. 

So I suggest you remove your bottom bracket entirely and then push the spacer all the way down into the bottom bracket space where it can be then cut, folded, spindled, and mutilated. 

Appropriately sized wooden dowels or PVC tubing would be your best bet if you didn’t want to mar the seat tube. Very long handled minus screwdrivers can be used if you don’t care anymore. An aluminum spacer may have cold welded itself to a steel seat tube and in those cases, chemical or thermal assistance may also be needed. 

Ps. I don’t actually see a seat post clamp on your bike in your pictures and so I’m assuming you do actually have one.
