So, this is how I'd write this chapter.
To appreciate this car, you need to consider the changes that make something like my '75 USA-spec. FJ40 a nearly obsolete car as far as a complete restoration is concerned. My year originally sported an early emissions computer, igniter-type ignition, and a pile of spaghetti vacuum piping that ties every part into one sophisticated system. For example, in '75, if you have a failed transfer case speedometer cable seal, you'll want to possibly watch for gear oil from the transfer case along the speedo cable into the mileage counter, or you'll have gear oil running down the firewall, and maybe issues with vacuum retarded timing, as it is all tied to emissions? Not long before that, there weren't sensitive electronic components, and vacuum diaphragms to deteriorate with age and use. Before the Exhaust Gas Recirculation system, that came with all USA-spec 2Fs, the oil was not exposed to as much exhaust in the combustion chamber - life was simple.
This FJ45 Land Cruiser represents the era, that was basically gone in North America by '75, much less '84. Once the electronic controls were onboard, a simple jump-start operation, saving the driver from being stranded, could create a voltage spike in the system, damaging the electronic ignition pickup in the distributor, before the voltage regulators detect the spike in voltage after you remove the negative jump cable. With the older points-type ignition, like you see on this FJ45, in the event of failure, you can make them run again with sandpaper and a screwdriver.
By '84, people in the States were driving on freeways, and the 'minitruck' had been Toyota's answer for a pragmatic pickup. The last year Toyota offered the FJ45 for the States was sometime in the late 60's, iirc.
