I just went out to check the 151 I have that came from a Jeep. It has a rear sump. I had not noticed that it is sitting in a wooden cradle that hides the pan. So there is a source. Jeep YJs I think, mine is from a 1980.
They were used in the Postal Jeeps, white boxes with sliding doors and right hand steering.
