The lettering on my PS reservoir top decal is is worn off and a search revealed a a similar reservoir with a yellow sticker like this one...
and then some with a silver sticker like this one shown on a Land Cruiser reservoir ...
Both of these stickers wrap nearly half way around the top, but a closer look at my decal shows that it does not wrap around that far. The reservoir on my 87 4Runner looks just like this and you can see the decal size is a little smaller ...
This suggests neither of the decals above are what was used on the 1987 (an possibly all first gen) 4Runner. Does your decal wrap half way around or almost half way? Can you read the lettering on your decal?
