Question about 67 SWB frame

[dave6672]

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!

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

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

Hopefully someone more knowledgeable will chime in

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.
