Assuming you have a 1/2 ton or 3/4 ton truck, you'll have a Dana 44 front end.

Locking manual hubs can be had from Warn (I recommend their Premium, #20990, about US$100 from Summit Racing @ summitracing.com... not cheapest but I'm sure they'll ship to you)...

There's also Milemarker:

they have lots of different models, or Superwinch:

I think you have "locker" (locking differential) confused with "locking hub". You *do* need a (manually) locking hub with the part-time kits.

Hope this helps; feel free to email me offline if you want more specifics /forums/images/graemlins/smile.gif

I use warn premiums in my '78. They're well made and work good too! /forums/images/graemlins/thumb.gif

Just as a followup, John mailed me offline... I think he's actually referring to the brake hub, i.e. inside the rotor, and is confused (rightly so!) with the drive hub on the end. English is confusing enough -- and then add silly parts names into it, plus the fact that the nearest NAPA store is some thousands of miles away... /forums/images/graemlins/laugh.gif

Anyway, I found some pictures of the various parts and hopefully that'll help us identify what he needs.

The, "brake hub" you're referring to is actually called a, "Bearing hub."

*That*, thank you. I know to look for it under brake parts and it's the hub that the brake rotor mounts to, but I knew it's not part of the brake system proper.

The 203 part-time kit from Mile Marker comes with the lock-out hubs. Grim did a great article in the product reviews about this kit. I've got the kit and can say it's pretty well made.

How's your tour going? Spent a year in Iceland at a site called Hofn. One of the better remote tours... /forums/images/graemlins/smile.gif
