Note 1: Phoned Heidts and the salesman didn't think it moved the spindles out but he wasn't sure. Some Chevytalk members report
the wheels remain in the stock position and some claim the wheel move out 3/8" per side.

Note 2: A ChevyTalk member phoned Heidts and the salesman said it moved the wheels out 13/16" per side, 1 5/8" total.
This Hot Rod USA page states 1" total. Use 1 5/8" to be safe
