[husker boxster]

Just went thru this with my 928 (update to thread coming). I ground the nut end flush with a dremel. Next step was to take a hammer & punch to them. Thankfully they all came out with some healthy whacks. My next step was to use a yellow benzene torch on them. The blue version doesn't get hot enough, supposedly the yellow one does. A yellow version costs $50 at Lowe's.
