IF you can't find it at a junk yard, just order one from rockauto.com. Here's some info that will save ya some cash if you do decide to order online:
Using Your Discount Code
Enter the code above in the "How did you hear about us" line of the shopping cart. If you are using our traditional HTML catalog, please click the "Apply" button to the right of the field. Your discount will automatically appear, subtracted from your parts order total. Orders using discount codes must be placed online. Phone orders are not eligible for discounts.
Please note: We sometimes get calls from people who put the word "discount" in front of their code and do not get the discount. Please enter ONLY the discount code, no other words or numbers. Code must be entered before order is submitted to receive discount. The discount takes 5% off our already-low prices. There's no limit on order size or the number of orders. Use the code for your next order, and share the code with friends, neighbors, relatives, the guy at the corner garage--anyone you know who works on cars or trucks.
This discount code expires on July 21, 2013; so don't wait!
