The easiest way to find one is to rummage through some glove boxes in vehicles in a salvage yard. There's a real nice chain of yards between Ohio and southern Georgia called "Pull-A-Part" where you pay a buck, put your tools in one of their wheel barrows, and you can spend all day there. Parts are real inexpensive and the yards are very clean and well-organized. You can do an internet search to see which yards have vehicles like yours.
