I believe that the BJ42 was last made in 1984 and mine rolled off the line in August 1983. The LX features 3 wipers, aircon (factory), rear slider windows... What else? Was the bull bar always aftermarket, what about the tow pack? Was the dual battery only factory in Canada? Do all the FJ/BJs of that generation have Hand Throttle? Also what were the original tyre specs - 31" (ORD) on 16" Polished silver Rims? These wheels measure 28" Outside Rolling Diameter and I am told that the rims are "original"... Any other characteristics of the BJ42LX from 83 I have missed?
