I didn't have a stock jack when I bought my car. I checked them out on eBay, and they are expensive, and have so many variations that I didn't know what I wanted. I ended up buying a cheap 2 ton steel jack, that is small for $40. I made a simple bracket, welded it to the floor, and secured the jack with a bungee. I think I will end up changing the bungee to a spring for better appearance. I think this is better than a stock jack. More stable and easier to use. Plus it doesn't weigh very much. It might even help with traction.
