I could be wrong but I think around 1988.

Thanks, this is an 88.

Correct. The change came with the change to "R" and "V" series, as opposed to the previous "C" and "K" series

So that would've been 87...

I think my 1985 C10 had that SPID but she had the Northeastern weight loss problem and went away to the big interstate in the sky in 2001.
I can't go look for a sanity check and I have CRS or so I'm told by SWMBO.

'87 used the previous (larger) style SPID.

This proves she's right... :lol::lol::lol:

"she" who?

'87 was the first year for the R/V designation, and used the large SPID.

The GMT400 platform was introduced in 1988, used the C/K designation and went the small SPID.

My 1987 v10 pickup has the smaller 3 digit rpo code only spid, not sure that it helps but I am seeing either here.

Wonder if when they changed over was plant dependent...
Keith might know.

FWIW, It wasn't a sweeping change across GM, the smaller S-series trucks had the newer RPO style stickers earlier. My 86 had it.
