That's correct. The spacer is integral w/the rotor & not a bolt-on deal. Mine are 1pc as well (same as the 88).

Measure from the rotors surface to the wheel mounting surface & that's the track width difference between a dually & the single wheel 1-ton & 3/4-ton widths. That's how duallys run the dual style wheel up front.

When you're looking to go w/big truck 22's on a dually app, if it's a moderate drop (>6" up front), you'll want to narrow the track width (or you'll be into the fender lip w/the wheel). Mine are too close & I have 16's still but there's a difference when rubber buzzes the inner structure vs aluminum. So they switch to the 1-ton/3/4-ton single wheel rotors, add the 8-to-10 lug conversion adapters, & then utilize stretched a-arms to put the wheel right where they want it (or they opt to use shorter arms w/the dually front hub but are limited by how much they can narrow things up).
