Funny how he doesn't show the front axle or the T-case!!

[Yewhi]

Yeah this has been for sale for a while. Earlier versions (months back) showed a bit more. It wasn't pretty.

I could be wrong but I thought in 1960 Chevy started supplying all 4X4’s with factory equipped four wheel drive, no more NAPCO products.

[b454rat]

yup. Only 1 tons were NAPCO. That one wouldn't matter anyways since he swapped the axle out. But not a bad price tho....

I haven't checked this thread in a while, it's good to see some new pictures. That green 57 is frickin' gorgeous, it gives me hope. I haven't got a lot done to mine recently. I'm hoping to change that soon. I've been busy on another car and trying to get it to auction this spring. I do have the transfer case and SM420 freshened up, pretty and ready to go. The front axle was all busted up. I ended up with 3 broke trunnions and had a friend repair those. It's all been rebuilt and back together. I have the engine work done, just need to assemble it.

That would be cool to own. Just a tad out of my price range at the moment though!

[HO455]

Great bump for one of my favorite threads. 58 GMC only $4400

Very rare original Napco factory 4x4 truck. Spent most of it's life in an old Colorado mining town. Surface rust only. Very solid body and frame. All bolts turn if you need to work on something. Nice running 283 V8. Electronic ignition. 5 speed trans. Clutch good. Exhaust good. Brakes work but hydroboost should be rebuilt for more stopping power. 4wd works fine. Operational dump bed and power tailgate. Lights work. Military tires have some dry rot but holding air fine. Everyone that sees this makes some type of comment about how they would hate to see this behemoth bearing down on them in their rear view mirror. Very one of a kind striking truck. Dual wheel chains on the sides were for Rocky Mountain winter running. Sold with Maine bill of sale as well as have the Colorado title for it. Call 207-239-87 zero four. If ad is up, Truck is still available. Emails that look fake will not be replied to.

[Yewhi]

That is beyond cool!

I have a question for you guys who know Napco.
I have a ford N600 Napco conversion. I believe from some literature i purchased that my front axle is the 7500lb version. I understand Napco used a lot of Eaton differentials on there axles. I'm just curious what mine would be. I wouldn't think the H072.

HO110 is the next size up. Those are typically in 10-lug rear/5-lug front mediums. Not sure what the next size up was from there.

[Peanutbutter]

I think the next up from the 110 is 13500, 15000 and then 17000. The trucks with 5 10 wheels and 6 hole Budd wheels must be HO 110 or 13500 axles and the locking hubs do not have the grease zerk in the center. the trucks like the two of mine that have 10 hole Budds have the zerk in the center and I think are HO 15 but that's not written in stone yet, still looking for more data.

Thanks guys for the replies.

That's a cool truck. I see you have another N-series. Don't see those too often...and I go to a few big antique truck shows a year. Same goes for the GM B-model.

Yeah they aren't very common, but I have seen more of them in North Dakota and Montana than anyplace else. The Napco truck is pretty rusty in the cab. I plan to swap the running gear to my grain truck. Everything should swap over. I'll just have a new rear driveline made since the grain truck has a longer wheel base. I'm not sure why but all of my trucks are 4 wheel drive except the grain truck.
