Pendragon used to say quite frequently that there were TONS of Ajaks laying in Colorado junkyards. Seems to me it might be interesting for somebody to make some phone calls, and take a trip out there to acquire as many as he can. Might make sense for a small side business of restoration and resale for a younger person. They are really quite simple, and it appears to me from looking at mine that I got off of Ebay that they were probably developed as a garage engineering project. A machine shop could easily duplicate one, and perhaps even improve it a bit.
