Canadian built for US consumption (does not have RPO Z49 Candian equipment).

ok thanks! and im not really sure why i have the other one circled i guess because it said 85 when its a 86 lol

Sure. Sept 16, 1985 calendar year would be the start of the 1986 model year. The new models typically come out in the September-ish timeframe.

A relatively early build, apparently. VINs start at 100001 and yours is in the 113,000 range.

My truck was built a year later (almost to the day) in Flint Michigan. Built on Sept 29, 1986 (1987 model) and they had already built more than 317,000 units in Flint.

did camper labels come on every truck? mine has one also but not sure if it really had a camper or it would have shown in the SPID right?

A Camper Special package would be shown on the SPID, because it had heavier-duty rear springs and tie downs.

Every 81-87 I've seen has had the camper sticker in the glovebox, regardless of whether it has the camper package or not.

Keith:

Was it 1983 that the SPID font was changed?

And what year was the SPID made smaller, showing only the codes and not the descriptions?

This is correct. Mine is not a camper special, either.

This I am not sure about and would have to check into. There may have been some plant-to-plant variation even within the same model year.

We might be able to discern that from this thread once we have more entries.

Here's a couple more to add ...

My 77 GMC Sierra:


And Dad's 77 GMC Sierra Classic:


A few things I noticed when comparing the two:

(1) Both trucks were equipped with factory dual exhaust but it's only listed on the SPID in mine. That's because (according to the 77 truck info kit from the GM Heritage Center) it was automatically included with the LF4 400 engine in Dad's truck.

(2) Both trucks were also equipped with the Z53 gauge cluster but again, it's only listed on the SPID in mine. Turns out that's included with the YE9 Sierra Classic Equipment. And I also found it interesting that it was still being listed as "GAUGES - AMMETER, OIL" even though these trucks changed over to voltmeters in 76.

(3) My 77 was built in Oshawa and Dad's was built in Flint. As a result, you can see some variations in the way they were typed up. Like how the "MODEL TK10903" is listed. And how the option numbers on mine are lined up near the right side of the column, while on Dad's they're aligned to the left of the column (and have a 1 prefix).

(4) Finally, they are both GMC's but neither one of them has the Z88 "GMC Conversion" code as described in this thread --> http://67-72chevytrucks.com/vboard/s...=621909&page=2
I guess some assembly plants just didn't bother listing that on the SPID.

Good eye, Ray.

Relative to the GMC option, it is a little redundant since the "T" at the beginning of the model number (ie "TK10903") also denotes GMC.

However - in my mind - it should also have had Z88 on the SPID. Seems like a factory mistake to me; I would have taken them to task on that one.

I think the Fremont plant started in mid-1986 with this style of SPID, I know I have at least one 1986 SPID that's the smaller current-like SPID. The other plants were either very late 1986 or 1987.

Actually Keith, I have found that Flint starts with 300,001 for Chevy and 700,001 for GMC. I've been doing a LOT of research on squarebody VINs and RPOs to compile a comprehensive list of RPOs by model year. Not sure why that is though since all other plants start with 100,001 for Chevy and 500,001 for GMC.
