Honestly? I don't know. The sticker set was the "toy accurate" set, even though the actual G1 Ironhide toy didn't have that marking. I'm guessing it's something from the actual Nissan Sunny-Vanette Coach SGL model deco?I love this pic! Pardon my ignorance though, but what is the significance of the "2000" logo on Ironhide? I get the yellow stripe, and it looks like you've used a sticker set with some other upgrades, but just wondering about the number.
I'm not too familiar with that vehicle but it looked like a deco that would have been used at the time it was new.
