KFOCI HANDBOOK Version 5.0 has the Wagner Brake service information from September 1948 and the Kaiser-Frazer parts list with exploded, numbered drawings showing part numbers for the individual pieces in the wheel assemblies, front and rear. I am assuming that this is where Custom got the files he posted.
All members on the books in the fall of 2013 got this update AT NO CHARGE then, and those joining since were supposed to get the Handbook ALSO AT NO CHARGE as part of the new member materials sent from the Club Secretary.
The handbook on CD is a perk for being a member of the club and whenever a new update is released all members get a copy of it.
