Rbv= Ranger Based Vehicle
ill bust it down in simple form
83-92 are the same(minus dash and front fenders/clip)
93-current are same(minus 3/4 door, dash in 95, and ifs in 98)
core supports/radiator changes break dowm
83-88
89-92(can be modded for 83 headlights/grill) if need be
93-94
95-97
98-current
firewall(only 2 designs)
83-94
95-current
doors(2 designs)(explorer doors and mirrors do not interchange with rangers)
83-92
93-current
the inner structure is the same from 83-last year, so the body mounts are the same minus the radiator support on the front for the 98+(frame horns are a little wider)
back window interchange
regular cabs are the odd ball, 83-97 reg cab back windows interchange
ext cab is 83-current, and 98+ reg cab(only cab that wont bolt to a 97 and older frame) share the same back window
2wd ranger frames are the odd ball, all other rbv are based off the 4wd chassis up to 97.
95-01 exploders have the same front suspension 2wd or 4wd as the 98+ torsion bar rangers
add more as i think of there are differences in wiring.
body lines are different on explorers but the floor pan for the front is the same as a ranger extended cab.
