Great overview on the Marlin story. I too lived through that time wheelin era and saw all the Toyotas were mall crawlers, lots of chrome. All my friends wheeled flat fender Jeeps. Me? well I had a different Japanese make that I built up. Early to mid 80's timeframe.
So you'll have the range box, 1.1 or 4.7, and the rear case with still work as stock? Until you do the LC case where you case twin stick the rear of course.
