No - the 04's have a traditional lead acid Delco, but the posts are on top. The leakers were the side terminal Delcos.
I would still put in an Optima. One thing to mention - the Optima's posts set further back than the Delco's. If you decide to switch, you have to straighten the end of the terminal from it's 90 degree bend to about a 45 degree bend to make it work.
there was a thread around here about this about ten days ago....I'll see if I can find it and put in a link.
