I just aquired a 1970 Ford Napco conversion, you can go to my profile and check out the pics....

 

are you sure it is a napco? ford started making factory equipped 4x4's in 1959 i believe, so i have to say it is probably not a napco conversion, but i guess i could be wrong
EDIT: i just checked out your gallery, and yes, it is a napco conversion. i can't see why someone would pay extra for a conversion kit back then. it had to have been cheaper to just order a 4x4 f250. this truck is an extended wheelbase truck, so i can only assume it was a special order truck for a business or farmer with specific needs, maybe a logging truck. do you have any additional background info on this specific truck? i am very interested in where it came from and why it is configured as it is.

 

From what I see, that used to be a dually dump truck. You can see the dual wheel spacers on it, and you can see the posts that used to catch the dump box

 

Napco did do 4x4 conversions for the 1 ton ford trucks, Marmon Hearington did most of the upfits after 1970, that's what makes this truck so rare. Napco stopped doing 4x4 conversions in 1960 for the 1/2 ton and 3/4 ton trucks. They did continue to do 1 ton and up until the early 1970s. For more history on Napco conversions you can go to www.Napco4x4.org they even have Fords on the website.

The truck used to have a funky narrow dump box on it, It still has the PTO shafts that ran the hydraulic lift for the dump bed. I am putting a flatbed on it and will use it for towing.

 

fwiw: Lots of posts for napco in the older truck forums here.

 

1959: F100/250's only. First F350 with factory installed 4WD: 1979.

 

thanks, but i know bill. until i looked at his gallery i thought he was blowing smoke up my butt. i didn't see that it was a one ton from his avatar, guess i just overlooked it.

 

The front diff being on the passenger side was a dead giveaway its a conversion.

 

like i said i didn't pay attention to his avatar until after i posted. i have seen a few chevy conversions in person, but never a ford. did they do any for dodge that anyone knows of?

 

No, Napco never did any for Dodge as far as I know. GMC and Chevy were the only trucks that had two options of either factory installation or installed by an authorized Napco installer, usually at the dealerships. Ford and Studebaker had only one option, an authorized Napco installer.
International Harvester and Dodge both went to the Spicer/Dana 44 closed knuckle front ends in 1956 for their 1/2 & 3/4 ton trucks. International Harvester used Eaton front axles for their 1 tons and up....I think Dodge did too until the Dana/Spicer 60 closed knuckle came out in the early 1960's. Dana Corp. bought out Napco in 1960, that's why you see the closed knuckle Spicer/Dana axles on Chevy and GMC 1/2 & 3/4 ton trucks after 1960... Napco continued to install 1 ton and up conversions on Chevy, and Ford until sometime in the 1970s.
