My truck, (pictured above) has redrilled front rotors and 1-1/4" spacer/adapters on the rear. While it had the truck rearend under it, it put the rear track even with the front or at least very close to it. Now with the narrower Caprice rear it's closer to how a stock truck is, even with the spacer/adapters. I also ground some out of the lug holes on some factory rally center caps to fit the 5.5-1/2" bolt circle.
Nice to now my truck is inspiring people
