THESE WERE only found in dealerships and you had to be a mechanic to get them, i have about 30 of them from 1966- 1975 tech manuals-816-242-4068 ----earliest one is 1966to75-- have wiring diagrams for seatbelt retractor switches--the real truth on how air conditioning worked in 1972-- has many dealer ownly info--35.00 each, these are very hard to come by, i've stored them for years and if i don't sell them in KC there's always the MOPAR NATIONALS, TAKE ADVANTAGE,GET THE ONE FOR YOUR CAR YEAR, ALTERNATOR WIRING AND TORQUE-FLITE MANUALS ---no only are they informative,but........ you put these on your MOPAR hotrod ,on the seat or dash at the shows
