Cabs....1/2, 3/4 & 1 ton......Whats the difference?

[m6z]

Are there any differences in the 1/2, 3/4 and 1 ton cabs? Are all the mounts the same or do they very?

Thanks,

[72freak]

It is my understanding there are no differences. Some may have the raised areas for the cab lights. Once you get into the medium duty they change a bit.

The 3rd digit on the VIN is the only thing.

The actual rubber mounts that go between the frame and cab are different from 1/2 to 3/4 or 1 ton but cabs are the same for sure.

Cabs are the same. My 68 was a factory 3/4 ton now it's on a 72 1/2 ton frame. Joseph

So could you get a 1/2 or 3/4 ton cab with the flat spots for cab lights? Reason for asking is I have a 1ton Gmc cab that I want to put on my 1/2ton Chevy. The 1ton cab has cab light recesses and I'm not sure if it'll look funny in the weeds with big wheels. Sorry for the thread jack.

Actually, I would go out of my way to put some lights in there! Something different and cool IMHO...

Sorry for hijack too

When I tore into my truck the first time I was met with a cab that was wasted so at 17 years old I drove from CT to SC in search of a cab I came home with a 1 ton with factory cab lights. The truck is a 68 K10 short step I have always liked it and only someone with knowledge of these trucks can ever figure it out and even then sometimes it gets by them.

the lights were a factory option on all pickups 10 - 30 series, in both c & K designations. They were only required per DOT regs on trucks built with no bed (or flat bed) and with the DRW option.

If you are talking about the same year being the same they are ,,but if you were to mix them with cabs from other years,,, I do know that the year 72 has no holes or raised area for the review mirror .. I learned this from Longhorn Man a few years ago..

[cpisani70@aol.com]

Thanks for the Correct info I was told more than once that those were only offered on 30 series , I liked the look of it so I never cared I just assumed they were right.

The raised pods began in '69 when the round base lights came out.

[m6z]

Thanks for the help guys. That's what I needed to know.

[cpisani70@aol.com]

So maybe that was what I was told years ago the cab was from a 69 C30 with raised pods and it ended up on my 68 K10. I remember when guys would see it some would scratch their heads then tell me the roof wasn't factory. Most of the time I wouldnt let on to what I did and leave them doubting themselves

So all of the 67-72 c30's should have the roof lights? Going to go look at a 67 GMC dually tomorrow night and it doesn't have any roof lights. I'll be sure to check out the spid.

[Longhorn Man]

all C/30s with dual rear wheels. My one ton longhorn didn't come with them.
I KNOW68 to date but not 100% sure on 67 and older.

[special-K]

'68 and earlier used chrome tear drop style with no special roof panel,if they had clearance lamps. The ICC mandated them somewhere in these years down to 10,000# trucks,which is what a dual rear C/30 is. Possibly began in '68 IIRC.
Here's a '67 w/o clearance lamps:

Thanks. Since we're on the topic. Do you guys know if the late model dually wheels are a direct swap for the old split wheels that would be on 67 C/30?

I've been thinking of a C/30 truck that I can use to go pick up future projects. Eventual LS or Dmax motor and maybe air bags.

[MrGoodpliers]

It has been mentioned already, but I'll add a bit. Cabs are same, but the rear cab mount brackets on the 3/4 frame are mounted lower on the frame rails to allow thicker rubber mounts.

[72freak]

Neither my 1968 C30 that I turned into the Dually Longhorn or my 67 C-30 dump had the raised area. Both came with the Yankee style lights Special K mentioned above.

[m6z]

Just looked at a 67 gmc dually. No cab lights at all. Orginal paint and nothing on the spid about lights.
