The short pinion end spacer is tack welded to the lock nut so may not be obvious at first glance. On S4 cars the spacers were increased in length to 2.0" and 0.53" to accommodate the change from 145 to 155 tyres.
Edit: There's discussion about additional spacers in this thread from a couple of years ago ... could that be where you saw it perhaps ?

Just to reiterate in reference to the previous thread, you can effect the spacers needed for a 26R, or in my case an S4, to accommodate wider tires and consequent fouling of the ARB via use of clip-on spacers. Can be installed in situ as well as dialed in to the precise size needed.
