Time to time, we may feature a part here so we can show a few more details about the particular item. This one is a really popular part. This is an excellent reproduction of the 1969-70 Windshield Washer Reservoir for the Mustang. We have included two extra pictures showing the Ford engineering number and the Ford Logo on the cap. The tooling was made using the original Ford blueprints and nice original patterns. The one that is or was available from Ford is a replacement that will work, but is not like the original part like this item. It is, of course, Ford Licensed. Order part number EG316.
