My "phantom of paradise" phantom dually project.

Something the board doesn't like about what I'm trying to post so I'll keep f'in with it until it doesn't hang when I hit "submit" ...stay tuned for the final version.



4th digit E is GVWR range 6,001-7,000 lbs

6th digit 1 is 1/2 ton

7th digit 4 is 2 door regular cab

So there you have it...someone stretched a 1/2 ton regular cab into a crew. Something else that's a good indicator is your lack of cab marker lights, which would be required if it were originally a cab from a dually, though of course crew cabs came in 3/4 ton and 1 ton SRW (which wouldn't have cab markers either) so that doesn't mean a whole lot. Finally, can't tell whether your roof has them or not but factory crew cabs have visible stiffening ribs in the roof panel, just like a Suburban does.

Most likely Centurion built it though I don't know enough about them to say what signs might prove it. I bet some people over on that conversiontrucks.net site I posted could tell you what else to look for.

By the way, the VIN decoding I just did is easy - I posted a VIN decoding card for all the details I know so far, over in the "Tech Writeups" section here.

whoa, brah I didnt know all this about my truck! mahalo for all the info brah!! I get one question, how they make the extra cab any way? they fab one up from scratch or they use another part of a existing truck and ad um on?

Beats me but one thing I'm pretty sure of is they're not stamping out their own body parts, it costs a damn fortune to make the dies and the presses required to run them are another fortune.

I figured conversiontrucks.net would have more info on this but I just checked, and I've seen more Centurions posted on other sites.

Does yours have the ribs in the roof? One pic I saw of another truck seems to have them but it's hard to tell. I really wouldn't be surprised if they bought a crew cab shell and rear doors from GM, you could do this, it's just damn expensive to buy a cab shell. The only thing I can't figure out is it's fed law you can't tamper with a VIN tag and of course that includes moving the tag to another cab. In most cases if you saw anything that involved needing a VIN it would have an "assigned VIN" sticker instead of the original tag, really going out on a limb here, maybe Centurion got special permission as a manufacturer of sorts?

Lotta speculation, but there's so little solid info out there about these. I didn't even know they existed til maybe a couple years ago.

Mahalo once again for all the info.

What made you decide to do all the researching about these trucks in the 1st place?

Love these trucks (GMT400 body in general) - what started me off was buying and modifying my first one back in '99, then rebuilding after it was stolen/stripped in '05. Took a lot of learning about differences across year models, for parts interchange. Later I opened up a GMT400-only salvage yard and ran it for 2 years. No matter how much you think you know, you learn something every day, if you wanna.

Before these, back in the mid-late 80's I also ran a salvage business strictly around the 60-66 models, which are actually my first favorite. Toughest/best looking trucks GM ever made. IMO.

Click the "Truck shop projects" link in my sig if you have a little time to burn. The '92 is the one I started with, the first out of 6 or 7 of these I've owned in the last 11 years, not including an assload of parts trucks for the business.
