It would
be wonderful if there were a source for replacements for the one major
part that just rusts away. If somebody could take a rusty old spider,
take it all apart, and make careful measurements of all the suspension,
steering, and motor attachment points, and create a digital 3-D model of
that in AutoCAD. From that it should be fairly easy to build jigs to
fabricate a steel tube frame that all the original spider mechanicals
would just bolt onto. Then somebody else needs to construct molds for
making pretty little bodies...
