1998 Neon Highline

I am working on a 1998 Neon Highline. I am replacing the waterpump. I am sure you know what that entails. What I have found is their is a washer AND a large nut (being used as a spacer) that the crankshaft bolt is going through. I was able to remove them without issue, but in trying to remove the pulley, the bolt (which seems to be too small) slips, as if it is stripping, when the puller bolt puts pressure on it. I am using a 3 prong puller. What I would like to know first is the size of the crankshaft pulley bolt and if there is supposed to be just one flat washer or a spacer as well? Next, where can I get the "special puller" needed to pull the pulley off? Thank you in advance. Boobala?
