This is a difficult question. It depends on the engine (4ALC, 4AGE etc.) and if it was offered in 1987.
Later years (89- up) offered the A420, but in any case you would need new mounts (if the car was offered with the 4 speed), otherwise you would have to fabricate new mount holes in the lower frame.
A factory manual would tell you if the 4 speed was offered.
Also the A131L shifting was controlled by a kick-down cable, while (I believe) tha A420 was controlled by vacuum.
You could also ask a junk yard if the 4 speed was offered.
While anything is possible you may wind spending a lot of money to get the extra gear.
