I bought just the perches from Classicparts. They have two alignment holes. One is in the center, and one near the edge. There are 2 ways to install them (offset hole toward the front, or toward the rear), giving you 3 different possible axle placements:
Stock position (perch welded so offset hole is toward the rear).
Medium setback (use the center hole).
Maximum setback (perch welded so offset hole is toward the front).
Think twice, weld once.
