The explorers engine mounts will bolt right into the rangers frame.
The stock 5.0 Explorer mounts and engine plates will work in 98+ torsion bar Rangers only. This includes 98+ 4x4, Trailhead, Edge and the newer Sport model that replaced the Edge.
On the other hand, 98+ 2WD coil spring frames (like the OP's) will not
accept the Explorer engine mount setup. Custom plates would need to be fabbed.
