Re: NAPCO visit...

Pics of NAPCO running gear. These are from a 65 1-ton but Bruce's truck is similar.


Front axle:





Passenger side steering knuckle:





"NAPCO" cast into driver side axle tube, hard to see on this one, it's had a rough life:





Front axle center section from the rear, it has a pinion load bolt:





Spicer 23 Transfer case tag, Bruce's may be a Rockwell married to the SM-420?:





T-case from the front:





T-case from the rear:





Rear axle from the front:





Rear axle:





Big PTO, makes the SM-420 look small:





Ramsey PTO winch with application-specific Ramsey mounting kit:





More pics of the 65 and a 62 6X6 here

That is a mean-looking '62!

Re: NAPCO visit...

Very cool front axle! I'm surprised Napco didn't just use the D70's like the dodges did in their heavy duty light trucks. They were closed knuckle as well.

Re: NAPCO visit...

Thanks for the pics of the H052/72 front axle! I heard of guys on Pirate converting the rear H052 to a front....I thought they were reinventing the wheel. I guess not!

Good Stuff!
