And its a Napco to boot,too cool.Did you ever see any of those sirens?When I first moved to Spokane after getting out of the Navy in 88 they still had them scattered around town,they were mounted on a skid on top of a big pole like 30 or 40 feet up driven by a V-8 engine(a chrysler poly 318 I believe).

I always assumed that Napco converted vehicles after production, kind of like the way Shelby modified Mustangs for Ford. From this pic, I gather that they modified chassis, which were slipped into the line when needed. Another layer of mystery!

Is anyone here familiar with the factory's arrangement with Napco, and how production was coordinated with them?

They did until 55 and then in 56 or 57 chevy took delivery of the kits at the assembly plant and installed them on the line.That lasted until 59 and then chevy came out with their new chassis in 60 and that was the end of the Napco's.Napco typically didn't do the conversion they shipped the kit out in a 1400 pound crate to the individual who bought the truck who could arrange to have his local dealer or a capable local repair shop install it or do it himself if he had the know how and tools.Supposedly it only took 3 or 4 hours to install and only required drilling 4 holes in the frame for the Tcase supports everything else bolted on in place of stock parts.They even recommended keeping the take off parts and returning the truck to original at trade in time so you could use it on your next chevy truck.Pre 55 were 3/4 ton only due to 1/2 ton being torque tube drive.They also made kits for Ford and Studebaker trucks but those were never done at the assembly plant.

We had a 60 or 61 4WD short box when I was a kid, rode like a tractor, but with a set of woods chains, would go through snow like you wouldn't believe.
My 64 is a long box and actually rides pretty good for an early 4WD especially with the stack of springs they used but I can see where a short box would be a rough ride.Chevy got it right the first time when they went went with the rear shackle front leaf spring,ford used a front shackle front leaf on 3/4 tons and thats why their ride is so harsh they didn't go with a rear shackle till the SD came out in 99,thats why the SD front spring swap is so popular on earlier trucks.Don does your Parisienne SC use the Grand Prix roof and wheelbase?Or is it more like an Catalina.

Same roof as a Chevy, 62-64. Same frame as a Chevy x frame too, so same wheelbase and all mechanicals, including drivetrains. Only difference was up to 62, as a six they had a 261, not a 235, then went to the 230 and 250. I'd like t0 know if any Cdn Pontiac body parts are interchangeable with any US Pontiacs.

All the engines appear to have point type distributors and a coil mounted on the intake. HEI's come out in 75. Looks like small blocks on the left and big blocks on the right. Your military right, Phil.
