Uhhh... I honestly can't remember what model it is. The only downside of the Optima is that it is about an inch shorter than a standard battery. Depending on where you buy it, they may give you or sell you an adapter spacer that sits on top of it so it's the same size. I solved the problem by sticking a scrap piece of 5/4 PT decking under it, about 8" long. Perfect fit, battery never moves.
You may also have trouble getting the OEM battery cables to reach with this battery. There is an additional set of side posts, screw type like GM uses. But unless they've changed, these posts are not rated for as high of a current as the top posts are. I hate the OEM battery terminals anyway, and mine were all corroded anyway. I got my nice mil-spec terminals and covers from Wranger Power Products.
The stock ground wire is probably too short. But, after ths many years it's probably all corroded anyway. Get some new #4 cable and make new ones. Your starter will thank you.
