i usually just burn the bushings out with a homemade propane torch or a oxy cetlen torch, much faster. It smells but it gets the job done quickly

they are still useable.

This is my first time changing them. Also I was OK with threading the inside and putting the bolt in and beating it out from the opossite side as I the Tap is part of my tool collection and the bolt was left over from anothe project so I did not have to buy them.
From what I have read on the this Forum it is not normal for there to be that much trouble removing them. I believe mine has an unusual amout of rust inside (the car came from the East coast some where).
