Partial VIN question (frame stamp)

[KevinK7]

I did search the forum, and believe I have my answer, but wanted to confirm.
I'm looking at a shortbed frame that I believe is from a '72 GMC. Am I correct in that the (red circled) portion of the VIN is the 'partial VIN' I should be seeing stamped on the frame?




My plans are to use this frame for my '68 C10. I doubt it, but will ask ...are there any differences with the GMC frame vs. the Chevrolet frame that I need to be aware of?
The added bonus here is that the '72 frame already has disk brakes, ...which I'm planning to switch over to.

Thanks in advance,

Kevin

Sent you a PM...

Your suspicions are correct as to the VIN contents on chassis....BUT

I have seen various different contents on the stamped numbers across 2WD, 4WD, C and K variants....
