Interested in swapping to read disks. From my understanding you only need the rear backing plate from a turbo loyale, the caliper, and rotor. I am correct?

You also need the brake lines (about 4" long). Rotor is easy enough, caliper and backing plates are a bit tougher. I believe some have used Civic calipers...

Found calipers on RockAuto.

Come down here to Hillsdale, Mi., and buy my '88 Wagon. You'll get everything needed for 5-lug swap, plus more.
