91-94 explorer, ranger 2.9L and 4.0L OHV will fit
MAZDA 5 SPEED is what you are looking for
You will need to use the master cylinder and slave cylinder from the same year truck your new transmission comes from
You may also research pulling your 2.9L and putting in the entire 4.0L OHV drivetrain from a 91-94 explorer, with a 90 BII its a bolt in affair
good luck
