Look on the back side of the steering knuckle...
8 bolts around the knuckles (small) ball = standard D44
12 bolts around the knuckles (big) ball = heavy duty D44

Also you should be able to tell by the front axle GVW on the body plate.
Usually (maybe always) the light duty has a tapered hub and a smaller lockout, The heavy duty has a straight hub and is bigger, same as all the 70s 3/4 ton chevys, lockout parts even interchange between chevy and heavy duty Ford, just the color of the plastic center was different.

If I remember right, the hubs were made by Warn with the Ford oval on the dial. My 70 CC has a HD, and my 76 CC has a LP 60. But I can't tell what GVW it has as the left door has been replaced, and the warranty/safety sticker is blank except for the vin.
