What body styles could you get a K30 in?

[davepl]

Shortbed? Longbed? Longhorn 9 foot? Stepside? Long stepside?

I have a hunch they're all 133" but have no idea. What would be the "coolest" K30 to own?

Chevy didn't make a k30 til the square bodies(~76ish) And I believe they were all long box single wheel or dual wheel.

It would have been a NAPCO conversion to get anything in a q ton drive line

NAPCO was not the only company offering 4x4 conversions to Chevys in the 67-72 time frame.

In that period Chevy offered several basic models of C30s.
Fleetside pickup, a Longhorn
Stepside pickup, 9' bed
Chassis cab, 133 & 157" wb
Flat faced cowl, 133" wb

The chassis cab models were also offered with dual wheels and a 14K GVW option using the H0110 axle.

Probably my favorite is a pickup, but SRW 4x4 conversions were very uncommon. My first choice would have to be a M&H stepside.

The other guys doing conversion :

Tulsa Truck Manufacturing started in 1969

MARMON-HERRINGTON

Have you been to my page? :-)

The later (square body) factory K30s were offered as regular cab (131.5"wb) and crew cab (164.5"wb) long bed (8') fleetside pickups and chassis cabs. But IIRC no square K30 stepsides as a regular production model. Just can't remember if they were a late 76 or a 77 introduction.

Same question for K20 and K10 I guess, then I'll know what I'm talking about. Problem with googling it is you can find one of everything and they don't mention when it's a NAPCO conversion or not.

I know there were 20,000 K20s made for '72, and they appear to all be 133 Longhorns so far as I can tell....

Not sure where you are going with this but in a nut shell.

Factory 67-72 4x4 K10s were swb (115") or lwb (127") in fleetside or stepside as pickups as well as chassis cabs for special bodies. Plus the Blazer (105") 69-72, Suburban (127") 67-72 and Panel 67-70 K10 models

67-72 K20s were all lwb (127") in fleetside or stepside as well as chassis cabs for special bodies. Plus the Suburban (127") 67-72 and Panel 67-70 K20 models

All factory C30s were 133" or 157"
The factory did not offer a 1-ton 4x4 between 67-72 as a regular production option. However they could be converted as ship through upfitter orders or at the dealer completion level with kits as provided from NAPCO or M&H for example.

Your C25000 133" is an odd beast as all 3/4 ton Longhorns were.
They sat on a 1-ton frame but had a standard 3/4 ton suspension with rear leafs. If you wanted capacity you had to order the heavier springs and tires. But the C20/2500 topped at 7600lb GVW. Where as the C30/3500 pickups could be optioned up to 9000lb GVW.

It is very unlikely you would ever find a 67-72 C10 or C20 period "converted" with a NAPCO package simply due to expense. You might find some on the earlier trucks as the factory phased in 4x4 production or used kits were transfered. Plus many people like to call anything 4x4 66 down a "NAPCO" just for the cachet name. Its funny to see production 4x4 trucks from say 59 and the early 60s (as examples) with NAPCO badges that never were.

Nice winter picture.
