Depending on where you are and how cold it is right now, a flat-head screwdriver and few taps of a hammer might do the job. If not, I've made very quick work of it on a few CRX's with a block of dry ice and the above implements. Just lay it out for 30 sec's or so and tap. The stuff wil shatter before your eyes.
