98+ Rangers may have coil spring or torsion bar front suspension. The ones with torsion bars are interchangeable with 95~2001 Explorer.
Most torsion bar Rangers use 1, B or F. The spring code is on the manufacturer's certification sticker on the drive door jamb. You can also take a caliper to the junkard and measure the diameter:
1 = 1.09" (<- this is Ford info. FWIW, my #1 bars measure closer to 1.10")
B = 1.06"
F = 1.03"
Torsion bars are computer selected on the assembly line to match vehicle configuration and options. Obviously, the #1 bars are the thickest and have the highest spring rate - these are usually found on optioned up Ranger 4x4 Supercabs although some have B's. F bars are found on lighter Rangers such as the 2WD regular cab Edge.
It's also important to know that the left and right torsion bars are different lengths.
