JWheeler908 posted a topic in Antique and Classic Mack Trucks General DiscussionI have 2 questions for a 1942 Mack FN that the shop I work at is restoring. I will start with the most important question. 1. Can anyone point me in a direction to locating the wiring manual for this model? 2. Can anyone confirm the amount of these trucks that are still in existence?
