Re: NAPCO Thread
 

That's the first I've seen of that beauty! I wonder if it was meant to have duals on the back? It looks awful narrow without them.
That's a Beast of a truck Ryan, looks to be in very good condition

Re: NAPCO Thread
 

I think that truck is a creation. A big pickup conversion on a cab & chassis. I don't think you could get a pickup on a medium duty. I think that is definitely a dual wheel rear, all there was for cab & chassis.

Re: NAPCO Thread
 

I saw one of these 48-53 GM trucks that was 4x4 and it was a dually as well. I believe the red truck is too it just doesn't have the outside duals. They obviously didn't make any 4x4 trucks then so anything 4x4 was odd. If I remember correctly Marmon Herrington did the truck I saw. It was cool and still was all original. It was at a historical society show. I'll have to dig up the pics.

Re: NAPCO Thread
 

The red truck doesn't appear to be a Napco- large 5 lug bolt pattern that resembles Dodge Power Wagon axles. Napco front axles used the same bolt pattern as the factory GM axle.

I follow him on Instagram and saw that thing on there the other day. Very cool find, he's got some nice other rigs too.

Re: NAPCO Thread
 

I was thinking it's a medium duty NAPCO cab & chassis that someone put a pickup bed on. It's heavier than an 8-lug 1t and that could be the 5 & 10 lug that the larger trucks run

Re: NAPCO Thread
 

I happened to come across a full detail of the red 52 Chevy while looking for the black Chevy 1 ton. I still haven't found it even tho I've seen it on the net many times.
This red Chevy has an interesting history and a bunch of.pics from when it was first found all the way through it's restoration. Here's a link to it.

Re: NAPCO Thread
 

That's really interesting. I wonder if it is one-off or if the power company had others built. I wonder if they built it.

Re: NAPCO Thread
 

Napco axles will have a diff cover- this looks more and more like an International front axle from a M-3-4 1.5 ton (or similar) truck. Like the description in the link says it was made up of post war surplus parts and the smooth axle housing is a match to the International front axles used in the 40's.

Re: NAPCO Thread
 

I made my comment before all this other info was given. I could certainly see it was not an 8-lug Napco and I thought the truck looked like it had the bigger sheet metal up front. I've owned a Napco, even rebuilt the front axle, so I know what the Napco axles look like.

This picture has been on the internet as long as I have. I've always wondered what it's story is. Appears to be a similar conversion
Attachment 2182918

I see the bigger ones with the wide 6-lug pattern and 10-lug. I've seen medium duty Fords Napcos with the wide 5. I guess it depends on what rating rear they have

Re: NAPCO Thread
 

I certainly didn't mean to step on anyone's toes and don't know what trucks you've previously owned-so my apologies. I see a lot of converted trucks get posted online and the term Napco gets used almost generically for any 40's or 50's truck that was converted to four wheel drive. The more I dig into my own Napco (even rebuilding the front axle as we speak) and learn about these early upfits it gets a little old seeing everything tagged as a Napco. I was only confirming what axle was used in the red truck out of my own curiosity than anything as I, and possibly others looking to learn, have not seen it before.
Anyway back to the topic at hand...

1955 Suburban conversion. Every time I see one of these I kick myself for not buying the one I could have back in 88. Oh there were good reasons not to at the time. Obviously this bring a trailer auction isn't mine.

https://bringatrailer.com/listing/19...rolet-3100-20/


This 1955 Chevrolet 3100 Suburban is equipped with the NAPCO 4×4 Powr-Pak conversion kit and is said to have remained in the current owner’s family since 2002. The truck is finished in brown with cream accents over black vinyl and powered by a 235ci inline-six mated with a four-speed manual transmission and a dual-range transfer case. Equipment includes 16″ steel wheels, a winch, a tubular front bumper, dual side mirrors, a split tailgate, and an aftermarket cassette stereo. The truck was recently inherited by the current owner after an extended period of disuse, and service in preparation for the sale reportedly included flushing the fuel system, cleaning the fuel tank and carburetor, servicing the brakes, and replacing the battery, fuel lines, starter, and valve cover gasket. This Suburban is now offered at no reserve by the seller on behalf of the owner with a duplicate California title.

Re: NAPCO Thread
 

Dang that thing is seriously cool! I wish I had the cash and room for another one.

Re: NAPCO Thread
 

Cool truck

Re: NAPCO Thread
 

I love that thing! There are some odd NAPCO conversions out there. The military and others had some mighty custom stuff, like cabovers, school busses, cabover school buses...

Last weekend at a big rig show & shine this guy had what started out as a, early-50s US Army Chevy NAPCO aluminum Stepvan. I took pictures but just got a new phone this week and managed to lose all my pictures.

This thing had a story. It ended up bought from the military and converted back to 2wd by Wonder Bread. Some other business bought it from them and painted it again. This guy got it and stripped all that paint down, plus the Army scuffed it with 80 grit so he had to work all that out to have the polished look it has now. He put it on an F350 4wd chassis, Accurides, coker bias-ply 6.50-16 M&S, hi-performance-built 6BT, with a 6spd out of a 2 1/2t IH. I really regret losing those pictures. That thing was neat. He still had the NAPCO Power-Pak emblems on it. Too bad it's no longer one, only in spirit now

Re: NAPCO Thread
 

^^^ If I was rich I'd have the biggest collection of NAPCOs on the planet.

But, alas, I have no money for such things...boo hoo. but, today I hope to be looking at a '70 Longhorn NAPCO conversion former Navy order. How historic? Top dog 67-72 4wd collector in my book. Listing says bad rust in cab. I have a 69/70 1t cab, air/high hump/cab lights just waiting for a truck like this. I want it so bad I'm going to go look at it anyway.

I watched this truck sit parked at a house nearby since the '80s. Always meant to ask about it. Sat so long it turned green. But I always had plenty of K/20s without rust and from the road I thought this was a factory K/20. Lord knows why the Navy needed a pickup with extra 6' bad enough to build such an expensive (for gov't vehicle) and unique truck. Decommissioned in '80. This truck sold a couple/few years ago in Marketplace. Now that guy is selling, $3,900. My camera is on the blink (needs battery) and I don't use my phone for this forum. If anyone is interested let me know in PM and I can send pictures by phone

Re: NAPCO Thread
 

Tim, My dad is here in NM visiting, we were looking at that navy truck On FB last weekend. Looks like it’s got some real potential. If you end up with it I can’t wait to see what you make of it.

Re: NAPCO Thread
 

Man, I was all over that thing. First caller, called and called (IM). Had to apologize if I was being a nuisance. The guy was so slow to respond, over and over again. It was still in the Mt. Airy area. That guy frustrated me so much I gave up. I have known of that truck for almost 40 years and I really thought this was it. The guy sure didn't act like someone wanting to sell something. I told him I'm a buyer sight unseen, too. Never got past IMs with him. I hope whoever bought it does it proper, as in 100% original. That would have been my antique truck show piece
