Many classic car / truck owners can have difficulty locating Universal Joints or Center Bearings. Most replacement parts cannot be located by a year, make, model lookup since most look up tables no longer reference a suitable replacement part. My suggestion is to contact a "joint clutch and gear" distributor and simply take your universal joint to them. They will size it accordingly and provide a suitable brand new universal joint replacement. If you are not close to a joint, clutch and gear distributor, simply call them and make arrangements to mail your old part to them for sizing and suitable replacement.
