You can get camber bolts many places from auto parts like NAPA to RockAuto. They should run from $12-$20 each depending on brand and source. Most sources list just 15mm for both the front and rear. But the fronts are 14 MM which none of the parts houses list for a Spyder. You can find 14MM bolts by searching for a Mitsubishi Lancer front 2002-2005. You can also get the bolts from Toyota.
