65 Cuda wheels..which way to go?

The rub point for the Chevy Celebrity caliper(used with the Scarebird kit) on the 14 x 4.5 wheel is the outer outside upper corner/edge of the caliper....even after grinding a considerable portion off the caliper outside edge.

The contact point on the wheel is just below the rim portion of the wheel on the transition.

Subsequently Scarebird indicated in an email to me that the 5.5 wheel was needed...which was not specified in their Aug 2005 Rev C instructions.

Their current website for instructions is:

Those current instructions also don't mention the 5.5 wheel.

Since the rub point is in the transition section of the wheel there must be some difference in the transition between the hub & rim for the 4.5 & 5.5 wheel
