Squarebody SPID Picture Thread

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?

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

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.

By the squarebody era, was there really any advantage (besides looks) to spending an extra $50 to buy a GMC instead of a Chevy?

Was there really any difference between them from 1973 on?


I'm not hating on GMC's, but I'm just curious.

Nope. Just emblems. Same engines, same option content.

The only advantage would be if your local dealer was a Buick/Pontiac dealer and sold GMC trucks rather than Chevys.

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.
