You have a 3.0l Vulcan engine
Here is a list of the cars and trucks, with years, they were used in:
https://en.wikipedia.org/wiki/Ford_Vulcan_engine
Not on the list? then it isn't a Vulcan 3.0l, and won't work
Ford Probe only used the Vulcan engine for 3 years, 1990-1992, so engine would be pretty old
Good read here on the Vulcan 3.0l changes over the years:

The car engines are mounted sideways instead of front to back.
So the coolant flow thru the heads and block is different, when engine is mounted sideways coolant goes in one end of the engine and comes out the other end.
In the Ranger coolant goes in the front and comes out the front.
So most recommend changing the head gaskets, since their openings change the flow pattern and are different gaskets for cars and trucks.
Some have not done this and say it hasn't mattered, so really up to you.
Flex fuel and gas only models don't seem to matter, the heads are different but people have swapped both ways and no one has reported problems.
You will swap all the accessories/brackets and waterpump.
Also upper and lower intake and oil pan, maybe oil pan pick up as well
