Correct you have a H41 and 3.70:1 diff gears.
The break down on model
F is for six cylinder petrol
J is the letter for utility type vehicle
4 is for 40 series
0 is SWB petrol model
L is left hand drive
V is for Van a hard top model
K is for a four speed transmission
J is for roll bar
A is for American market
Your not having a J and A means it didn't come with a roll bar and is a general market vehicle. You 2F would have have all the US emissions. That means a earlier style air cleaner rather than a narrow oval air cleaner that was over the valve cover to make room for emission on the engine. With the wide jump seats that roll bar was most likely added by the PO here. Guessing that may be the case with the heater also. The factory fog lights are rather small (I have a few sets) and do not draw much wattage. Would suggest using a pilot relay if you plan and installing some higher wattage off road lights. Wouldn't trust 40 year old wiring to handle a load Wasn't meant for. As for A/C not sure a canvas top would work here that well. Planning a factory type A/C but also planning on beefing up the insulation in the cab to help.
@murf has 82 with A/C that works well. But it's not factory and the cruiser is V8 powered.
@LandCruiserPhil did the build.
