This is a brand new and very high quality drop in oil filter element. This is for the CJ2A and CJ3A with the smaller oil filter canister. This is too small for the Military standard. This is a very hard to find item if you want to stay as close to original as you can. The civilian oil filter canister has a 4″ to 4 1/2″ opening under the cap. These are all US MADE!! Purolator, Wix, and Fram brands. Sorry no choice of brands. This filter is 3 3/4 across and 4″ tall.
