The first dealer I went to, which is about 10 miles from my house, didn't have any in stock, but could see on the computer, that another dealer had four in stock. So I drove another 20 miles to that dealer to get it. The second dealer told me what 135sohc said above, that there are lots of applications over a span of more than 25 years.
BTW, Dodge/Chrysler/Jeep sales must be doing well. This large dealer was literally packed with customers Saturday morning, and it looked like every sales person was busy working deals. Lots of people were test driving new Jeeps.
