So it turns out the first code was XUZ which is the front tire size 31x10.5R15, still coming up blank on the 23D and 29K codes.

That is odd your SPID does not have friendly name descriptions.

I have just purchased a '87 jimmy and while waiting for some pieces to arrive i thought I would check into the RPO codes to see what options were selected when new. I have gone through just about every post mentioning RPO codes and have deciphered most of them, but I still have a few left overs that I cannot seem to find. Can anyone translate these last 3 for me please?

XU2
23D
29K

Thank you

I'm sorry - I'm spending way too much time on this -

Another thing you could do would be to send away to the Heritage Center for your original build invoice. That would tell you all the build codes (and I assume option names), time built, original selling dealership, pricing, etc.

It was $50 when I did mine.

All square SUVs were built in Flint (as supported by the OP's SPID, which shows a VIN code of

H = 1987 model year
F = Flint Assembly plant
500xxx = sequential portion of VIN)

So - to summarize - two vehicles built in the same model year in the same assembly plant down two different lines: two different SPID styles.

Mine's a Chevy, his is a GMC. Maybe that's the difference?

Or maybe when during the model year it was built? Mine was built in September of '86.

Hi Kieth, I didn't know that GMC had there own assembly lines that were not shared with Chevrolet.

At the top of your SPID what does the typed number 515906 represent?

Hi Keith, Is the vehicle invoice, build invoice and dealer invoice the same document? Also at the dealer would there have been an order invoice?

Not quite correct.

Line 2 was Blazer/Suburban specific, but both Chevrolet and GMCs went down the same line.

Similarly, Line 1 was specific to pickups only, but both Chevrolet and GMC pickups went down that same line.

GMCs were about 1 out of every 9 builds.

Chevrolet VIN sequence started at 100001 and GMC VIN sequence started at 500001 for this particular year.



I do not know.

It is not the order number, since that appears at the bottom.

I also know it is not the build sequence number, because my sequence number ends in "87".

I don't have any guesses beyond that, unless it is some kind of vehicle indicator from before the General Assembly build sequence was established (Flint has the opportunity to shuffle builds around after body shop/before paint, and again after paint but before trim).

Hi Keith, I listened to your interview on c10 talk which was really fascinating. It takes me hours to try and aligned the fender gap. The assembly line only had one minute and would use three body shims until someone down line complained about the gap. After the fender was aligned did the fenders get another shot of paint? I ask because some of the fender bolts are the same color as the fender.

Good Evening,

I have a 1985 K5 Blazer with Paint codes 29 Midnight Blue and 21 Lt Blue Metallic with the two tone package the Midnight Blue was the primary color and the Lt. Blue was the center body stripe.

My code for 23D is for the LDD4 High Back Custom Cloth Seats (Blue)

My code for 29K is for the paint code for the fiberglass top. (Midnight Blue)

Look at the bottom of my glove box tag numbers showing on left and right side.

I hope this helps.

If that is the case there should also be a YUZ (rear tires) and ZUZ (spare) code.

It was structured this way so that a customer could buy different rear tires than front tires (and different spare, too).
