Hi! New Mud member here but excited to learn more! Background: I'm looking to buy and interested in a 70 series RHD preferred, diesel, and manual transmission 73, 77, or 78, not Prado (Not too strict on or deal breakers on any of those however, just preferences). Question(s): What year models or 70 series models came with factory lockers/ triple locked and how will you know? Will there be similar telling signs to look for when buying such as the K294 number on the 80 series door plates? Or the diff lock turn knob by the steering wheel? Because the 70 series has been out for so long, I'm just unsure when they started having them. Appreciate all info! Thanks!
