This is an NOS ignition switch retainer bezel, Ford part # D27Z 10852-A in the original Ford box. This ignition switch retainer was used on all 1972-1977 Ford Couriers and Mazda Sundowner pickup trucks.  The retainer is made of a durable plastic which is threaded on the inside. It screws onto the end of the ignition switch housing and holds the switch into the dashboard.  The inside diameter of this bezel is 13/16." These bezels are known for cracking and the threads wearing out from.  NOTE: The original factory box will only be supplied with the last bezel or if you purchase all of them. Perfect for replacing a missing or damaged ignition switch retainer bezel or for a spare should yours break. See my eBay Store for more Ford Courier and Mazda B2000 pickup truck parts.  We charge actual shipping only and are always glad to combine shipping on several auctions or you would be welcome to pick them up.  Thanks!
