Fitment is the whole point here: this service and repair manual is built around the 1994 Lexus LS 400 as Lexus released it that year, down to the 4.0L V8 (1UZ-FE) under the hood and the trim it left the line in, so the specifications and torque sequences you work to are the ones written for this car and not figures borrowed from an adjacent model year.
