1996 Geo Tracker 2 or 4 door make a difference

The best thing to do is call a dealership's parts department. The GEO was manufactured by Chevy so call them up and ask that question. I found (in other cases) that a parts store lists diffrent parts for something small like a 2 or 4 door vehicle and when I called the parts guy at a dealer, I was told that they are one and the same or, in some cases, diffrent but are interchangeable. When all else fails, I find calling a dealer (who has always been helpful) is the way to go. They also go through parts stores and knows the in's and out's of those scenarios. Be safe.
