We have a '92 Ranger STX, 4X4, 4.0, 5 spd.,E T/Case, and manual hubs. It seems to be all original and likely a Sport Rider as it has the leather wrapped steering wheel, power windows, A.C., cruise control,cloth striped seats like those pictured,with the power lumbar and under thigh extendables, 3.73 gears with Traction Lok rear, not sure of the front diff., and it has coil spring suspension as well as front and rear sway bars. We bought this truck for a toy and so far it's been a project, new u-joints, brakes, windshield leaks, broken/rusted rear spring mounts, etc, etc... and the beat goes on. If it wasn't such a good runner we would junk/part it.
Soon to get a fresh bed, driver side door and both rear quarters for the cab.
If it is a Sport Rider we might not modify it, at present we have a Garrett Turbo, steering wheel and both seats from a T-Bird Super Coupe that we are about to install mainly because the stock seat bottoms hammer our butts when off road and they are a bit uncomfortable compared to our other vehicles, Lincoln Mark VIII, Expedition, Mountaineer, and a Monterey Van. We don't mind the rough ride, we just don't enjoy the harsh seats.
In any case does this sound like a Sport Rider truck to you guys with knowledge?
