Whoa
Hiding in plain sight just in LA area (look them up):
-Andy Palmer Coachworks, Sun Valley;
-Steve Hogue Enterprises, Torrance;
-Drew Serb, Martinez-north; and
-McCluskey Ltd, Torrance
All of these are either McCluskey alumni or have a McCluskey buck and are accurate.
These shops can either 'panel-beat/english wheel' a correct car or take a Kirkham and re-contour the front clip to AC form-not uncommon.
Serb does not build retail, but does quietly generate cars when it wants (McCluskey buck).
