C8TZ-4537-C VINTAGE FORD 68 LT/MED TRUCK RR AXLE & DRIVE/COUPLING SHAFT SPACER NOS.  This spacer had been stored in a home garage in its original Ford paper packet since at least 1985, probably much longer.  The spacer appears to be in very good condition except for some surface rust spots which can be seen in the pictures.  The paper packet held up pretty well, also, although it does have some garage wear on it.  We could not find a comparable listing on the Internet as of this time, so we used the Fordification I.D. system to match this part with the 68 light to medium trucks (F100, 150, 250, 350) and the 68 Bronco which we noted in the Inventory Book 7 years ago,  The suffix "4537" falls within Ford's parts category of "Rear Axle & Driveshaft & Coupling Shaft."  Please make sure this part will work with your application before purchase as we are selling As Is with no returns. We use USPS Priority as our default shipping method.  We might be able to lower the shipping cost by using USPS Ground Advantage but we need a plain box suitable for shipping this item.  If interested, please message us before purchase and we will look for a plain suitable box.  We will then revise our Listing to reflect the lower shipping cost.  Please message with any questions and thank you very much for your interest.
