This guy lives about 30 miles from my house and I was thinking about going and looking at them.

Does anyone know anythign about them? Are they actually GMC axles or what? They look to have birchfield joints sp?.

only truck I ever saw using them

i know with 50" tires & chains this thing could go awesome places.

There was a company that did conversions for GM in the early fifties, can't remember the name or what years they came in. They are closed knuckles, which look like Birfields, but house a regular u-joint. I don't think Chevy actually started a production 4x4 till late 50's or early 60's.

Did a quick search, found this link . http://www.napco4x4.org/history.htm
According to this it doesn't use a u-joint like the closed knuckleDana axles but instaed used a form of CV joint. You might find more info by searching for Napco.

I would imagine parts would be hard to get for it or at least expensive. Really don't know though, so I'm just talking out of my arse!bsflg

axle

Though it is always good to have a heavy duty axle, that one might be tough to rebuild. The axleshafts will be hard to find and then it looks like the brakes might be missing the cylinder? What is the condition of the drums? Can you get brake shoes, can it be converted to disc brakes? Looks like lots of work but would hate to see you get into it and then not be able to find a part you really needed. Also wonder what that wheel bolt pattern is and can you get wheels for that?
Not poo pooing it just my .02 worth.

It's one of those things probably best left to somebody doing a restoration, somebody needing it to complete an old original would probably pay top dollar for it.
