Have a 92 Daytona iroc. Doing a brake job and found decent crack in the passenger side backing plate under the ebrake setup. I can find a new one for 230.00.... But, would like to find a used one. This is the single piece the calipers bolt to and that bolts to the spindle and axle. Anyone know where to get one? Can't find one in junkyard in Ohio. Searched lebarons, spirits, etc...
