Hello and glad to hear you're putting a few more KFs back on the road! About your comment regarding the community not fully thriving, this phenomenon is not peculiar to Kaiser and Frazer automobiles. Many clubs, including the venerable AACA have seen a drop in both membership and overall participation in the last few years.
