Nick,
In order to make sure you get the correct stickers made, we have to determine if your '86 was originally a car for export sales to Canada or was it originally a car sold in the US that is now in Canada. The stickers are different.
1. Is the factory speedometer still in place? Do the larger numbers represent kilometers per hour (car originally sold in Canada) or miles per hour (car originally sold in US)?
2. If you do not have the factory speedometer, check the emissions label on the heater core. Big black sticker on top of the heater core where the A/C lines go to or look on Russ's site for an example. At the bottom of that sticker is the text "THIS VEHICLE CONFORMS TO US EPA REGULATIONS APPLICABLE TO 1987 MODEL YEAR NEW PASSENGER CARS". This is for an '87 car that was originally sold in the US. A car that was originally sold in Canada will have some reference about compliance with the Canadian equivalent to the US EPA. And that wording may be in French.
If you are sure that your car was originally sold in Canada, then your trunk SPID label would look like this....Notice the wording at the bottom is in French. This '86 GN was also a car for export sales to Canada and made the second week of June.
You are lucky that the car was made in June. This is the time frame that the SPID labels no longer had the clear adhesive tape covering the sticker. Also, June '86 is when the sequential build # for the car appeared on the SPID label. 179293 was the build # for this '86 GN.
If you want, PM me the last six digits of your VIN and I'll look up in my records what an appropriate build # would be for your car. I don't know that anyone would be able to tell you that # is wrong. Records were not kept. But I have a few '86 GN records made in the second week of June that I could lookup. But I digress...
Let's make sure you car is actually a Canadian car first and go from there.
