VTO Retro 4 on a 280ZX Strut

The 73mm center bore on the 13x7 Retro 4 wheel provides plenty of room for the 280ZX hub snout without any modification. The Retro 4 has the same problem as the original Libre, the caliper mount just barely contacts the inside of the rim. If the outer corners of the caliper mounts are ground down, the wheel fits with plenty of clearance. The edge of the rim is .5" from the strut tube.
