The Italeri FLD 120 is very accurate. The frame, drive line, cab is virtually spot on. Remember, this subject was originally issued in 1995 by Italeri, which would make it an early FLD 120 edition. I'm not sure if the Cummins NTC was an option in the FLD back in the mid 1990s. All of the early model FLD trucks I have seen had the Detroit Diesel Series 60 Mark 1 power plant. The Cummins NTC was standard for the FLC model, which represents a mid to late 1980s subjects.
My FLD was built in the late 1990s. I used the Clint Freeman resin Detroit Diesel Series 60 Mark 1 instead of the kit Cummins NTC engine. The Italeri Detroit Diesel that is used in the Peterbilt kits represents is actually a DD Series Mark 2. For the sticklers, to use the MK 2 DD as a replacement in the Italeri FLD 120, a second generation FLD would have to be crafted. ex. integral sleeper and cab, condo roof, etc.
