Ford doesn't do a very good job of supporting older vehicles when it comes to parts availability. Your best bet is to find a pick-your-own-parts salvage yard. If you're between Ohio and southern Georgia, do a search for "Pull-A-Part". I've been to 16 of their 23 yards. All are very clean and well-organized. Employees and customers are very friendly and parts are real inexpensive. You pay your buck, throw your tool box in one of their wheel barrows, and you can spend all day there. You can search for vehicles like yours on their web site.
