Not to confuse things (I have 881/906 but it's been awhile...), but measuring the spring is more important than what the labels say, as the driver-side spring should be the taller of the 2 by a bit to compensate for battery/driver/fuel load. I remember reading somewhere (search these forums) that some OME for the Australian market have driver/passenger labels reversed because they run RHD vehicles.......
Sry - I reread your question. What year is your Runner? I assumed you were running the 906 in the rear, but maybe
not....
One more thing - LOL - so I clicked on your profile in case you had some model year info inf there and I noticed that one of the foum vulture scammers messaged you & was trying to get you to buy something from his friend - 99% sure this is a racket. Had one of them on me a while back, too.
