Question about 67 SWB frame
 

I bought this 67 about two years ago and am just now working on it. I noticed a number stamped on the frame that clearly appears to have a 1979 date. This stamp is located on the side of the frame right under the driver’s door. Does anybody recognize this type of stamp in this area? I’m not familiar with square body frames so could the truck have been framed swapped years ago with a 1979 frame?

Both of my 72’s have the VIN stamped on the frame of the driver’s side near the steering box. Did 67’s have the VIN stamped there as well? Mine has nothing stamped in that location.

My VIN number on door jam plate and SPID match each other and the truck’s options match the SPID. However the VIN plate does not have rosette rivets. Did 67 models use those? Just curious.

Thanks for all input!

part number for frame rail

some did some didn't has been my experience

yes they did have rosette rivets

Re: Question about 67 SWB frame
 

Yep my 67 has no vin frame stampings either. But It does have numbers like your pictures on the side of the frame too. That's a nice little truck. It's possible someone painted it and removed the plate although it looks pretty original.

I'm also curious about frame documentation. I was able to find this information although it doesn't prove anything it may help you feel better about your frame.

GM Parts Wiki has a listing for 3887701 in the Parts History Catalog P&A 30H January 1973

3887701 USE 03913179 11-67

Part number 3887701 was substituted by 3913179 in Nov of 1967

so 10-7-79 is some type of manufacturing code and not a date

Hopefully someone more knowledgeable will chime in

Going further down the rabbit hole

3887701 USE 03913179 11-67
3887702 USE 03913180 04-67



http://www.gmpartswiki.com/getpage?pageid=68743

3913179 USE 03935801 03-68
3913180 USE 03935802 03-68



http://www.gmpartswiki.com/getpage?pageid=221072

3935801 68-70 Ser. 10 W/115 WB (exc. 4/WD leaf spring) Left
3935802 68-70 Ser. 10 W/115 WB (exc. 4/WD leaf spring) Right


So it looks like part number 3887701 is for a 1967 C10, short bed, coil spring, driver's side (Left) frame rail.

Thanks for the responses and this information, cbeerman. It has been very helpful. I guess the number on my frame that looks like a date on my frame is actually some other part number of sorts.

Re: Question about 67 SWB frame
 

Adding some questionably helpful into here? I just got to stripping the frame of my ‘67 GMC 2WD short fleet and have these markings I came across.

DRIVERS
3914401-310
3-30-110

PASSENGERS
3914402-310
4-4-110

VIN tag has rosette rivets, has CS1570D on the VIN tag, CS1570-120 on the cowl, CS1570 on the inside of the drivers frame rail…..then a bunch of 507, 495, 1116 markings on the firewall. No idea what these mean.

There is also something cryptic on the inside of the drivers frame rail.

No VIN stamp on the frame anywhere unfortunately - causing me a hang of a time with the local regulators on having a VIN verification done. They’re adamant they need to see the VIN in 2 spots. All I have is the door. No SPID, no frame stamp like my ‘68 proudly shows.

I hope something is helpful here??

Nice truck!
Never heard this before I will have to check my frame for the VIN #

Re: Question about 67 SWB frame
 

And I thought Vermont was the state everybody used to get easy registration when there is no valid title?
I can't say if your local motor vehicle bureaucracy would buy it, if you had a fresh SPID printed and mounted on the glove box lid. But there are artisans who can print fresh SPIDs. That would be your two forms of ID.

Here is a link to Jeff at Out in the Shop. He can reproduce a SPID if you need it

Re: Question about 67 SWB frame
 

The ID is stamped in several places on your truck. If these sharpers are so smart, they know where those places are and can check them. Pretty sure there's one on the firewall at the heater box. Law enforcement has the particulars, for obvious reasons.

Re: Question about 67 SWB frame
 

Thanks Dave - will check it out.

Fake News? I haven’t read of any other place on these trucks you’ll find a vin except the SPID, the door jamb, the frame, and maybe just maybe a build sheet stuffed in the seat?

New cars are stamped on damn near every panel. I took my ‘68 apart down to every last nut & bolt, and the only location was the door jamb and 2x on the drivers frame rail. SPID had been removed and there was no seat.

Re: Question about 67 SWB frame
 

Not "fake news", and I don't appreciate that accusation.

Re: Question about 67 SWB frame
 

Are you saying the VIN is stamped on the firewall near the heater box? I had not heard this before. I will have to look now.

Re: Question about 67 SWB frame
 

Not trying to be accusational……sorry if it came off that way. This is the first I’ve heard or read that a VIN is elsewhere on our truck bodies. Could you post a pic or two for the group?

Re: Question about 67 SWB frame
 

When I had my 1970 Blazer completely disassembled, I only found 5 locations on the whole truck with either full VINS or partial VINS.

They are as follows:

Main stainless steel VIN tag - Full VIN stamped

LH Door Safety standards declaration decal - Full VIN printed

Glovebox SPID decal - Full VIN printed

LH frame rail near steering gearbox and PS pump on top surface- Partial VIN stamped

LH frame rail top surface in the vicinity of where the drivers seat would be located - Partial VIN stamped

My Blazer was manufactured at the St. Louis plant.

Example of the partial VIN:

0S123456

0-Last digit of the year 1970
S- St. Louis assembly plant
123456 - VIN sequential number. Must match last six digits of VIN on tag on door jamb!

Chalk markings is all I have ever seen other than the frame rail stamps and the VIN tag..
