Interesting truck.

I won't be able to help much with the axels and wheels, other than mentioning that the "7.20" on the tag should be the gear ratio.

If no one answers in time, you might want to check with the boys over at Stovebolt.com too (at the Big Bolts Forum).

They are pretty knowledge-able with stuff like that.

it is not a factory 4 x 4. factory only made them up to 3/4t. there are 2 options here. 1 is that it is a Napco 4 x 4 setup. there should be a plate some where on the truck that says Napco. 2 the other scenario is that an individual built it that way.
do you have registration for it. f it was properly done it should be stated on the registration.
back yard, I doubt it will be on the registration

i do not have any registration with it the guy i got it from lost it years and years ago in a house fire i guess and i have not tried to get any for it yet as it is no where near streetable yet... i was thinking that it was a napco but i couldnt find anything on it that says it is or isnt for that matter... again i was told that it used to be a cherry picker truck for an electric company and the guy i got it from said it was just a cab and chassis and he had a box laying around so he put it on in dreams of making it driveable again some day( alot like my dreams) but never got around to it.

[padresag]

it more than likely is a napco then. get your MVO to run the ser# to get the last registered owner and see if you can get them to sign it over to you. if the PO had it reg and lost it in afire then I wouldn't foresee any problems

All I know is that the truck is badass!

It's a factory truck, model KV4000. Standard engine 305, optional 351. Standard FD070 front axle, if I remember correctly. H0150 rear axle standard, three different rear axles optional. SM 420 trans standard, SM465 and maybe two others optional. I have the full factory maintenance and service manual for it, NO ITS NOT FOR SALE.
If you'd like to part with the truck let me know!
Best regards,

the 4 x 4 is not factory, the truck is. the truck may have been ordered that way, but Napco did the 4 x 4

Looks cool to me either way. Love seeing the big bolts with conventional beds. Looks badass.

i really appreciate all the input on this truck guys

thanks! i have to modify the box a little bit to get it to look right on the truck though im going to have to widen it a little bit and extende the front of the box about a foot so that there isnt a huge gap between the back of the cab and the box but that is not real high on the priority list right now i wanna get this thing running and driving again first then worry about the body

Must... Have... More... Pictures...

You can't just post the one main picture of that beauty! I'm pretty sure that's against the rules around here! LOL

[T Herder]

I don't know where you can get a manual, I've had this one forever. I've attached a file to help you identify your axles. If it helps the manuals name is "GMC Maintenance Manual Models 1000-5000, GMC Truck & Coach Division X-6523, published August 17, 1964 General Motors Corp."
