One of the pleasures of owning a Jeep is tinkering with it. There are lots of small and easy projects that you can complete in your own driveway. This is one of my favorites. Yes, there are complete kits you can buy that bolt right on, but how much fun is that? I bought a few parts from the local bike shop. No buying over the internet. No shipping charges. And, I kept my money in the local economy. All in all, a good deal.
I explained the project briefly to the owner of the bike shop, telling him I needed a gear shifter and about 6 feet of cable. Five minutes later I had my parts and it only cost about $15.
