It's not so simple, as most of these regulators are built to race in the "retro" class which requires stock type ladder bars. Those ladder bars aren't compatible with the JC steering system without them being heavily modified, hence the JC shapeways ladder bars. The rest of the parts can be run stock or with Hesse substitutes.
