Anyone know how to get in touch with Everrett or Zeiger? Are they still in business? I heard that they are or where making parts for the Stellings extension boxes? Never an answer at their numbers on the site which hasn't been updated since 2014. Not a good sign I suppose.

Send him an email. I bought some misc Zeiger steering nuts and bolts from him 2 or 3 months ago no problem. Did it all through email.
