Jon, my experience with clubs includes the Vintage Chevrolet Club of America (VCCA) and 3 of its local groups called "Regions". I have also partiocipated in events with some other clubs.
In the approximately 50 years that I have enjoyed the car hobby I have not found any groups outside of racing where even a significant minority of members actually do any work that requires creativity and skill.
Most guys I have met either order parts from a catalog and run only those items that are for sale that way or pay others to do everything.
Forums like this seem to be the places where actual gear heads "meet" and share information.
