If you can get the pins to rotate they will come out. The problem is the end you taped on may be a bit mushroomed. Cut the pins in the middle with a hack saw blade and then try pull them out from the ends.
Or better yet if you can cut the ends off the pins also, you can punch them through pretty easily without having to push a lot of the rusty pin through the hole.
Be careful that the penetrating oils you are using are not running down on the dust boots. These lubricants can swell the rubber seals.
I would stay away from heat now that you have soaked everything. These penetrating oils are very flammable, even if they appear to have dried up. So be careful with this idea.
I'm afraid you going to have to get tough with it. Man over metal.....and rust!
