No, the club does not have a 25 page interchange manual. Rather, an appendix to one of our older Handbooks (a manual that outlined the various models KF and Willys produced) was published. It listed items available at that time from NAPA and other sources for tuneups, shocks, brakes and cooling systems. That list was something like three pages in length.
One or two club members have assembled crossover lists but I haven't seen any available from anyone in some time.
