There should be a data plate somewhere on the transmission that shows the manufacturer and the series number. It might be buried under decades' worth of grime, or even be missing altogether.
Most of the Roadranger transmissions use a double-disc Spicer clutch that pulls, not pushes with the throwout bearing to disengage. The clutch discs fit inside a deep counterbore in the flywheel, and there's a "floater" plate between the two discs that splines into the recess in the flywheel. There is a threaded ring built into the pressure plate that is adjusted in or out by turning it with a specially-shaped pry bar to achieve just enough clearance for the discs to disengage when the clutch is depressed.
Adjust the pedal linkage first, to apply the small, single-disc brake at the back of the throwout bearing when the pedal is pushed all the way to the floor, then adjust the clutch disc engagement with the adjusting ring. There is usually a sighting window built into the bellhousing to eyeball the throwout bearing, and to use the adjusting pry bar. When everything is working properly, lock down some anti-rotate brackets on both adjusters to prevent the settings from slipping. Unless the clutch really gets abused, it's unlikely you'll need any more adjustment for a long time.

Hevi Hauler, I posted my reply before I saw yours! You did a better job of explaining the procedure!
