As Ben pointed out, the drawings in RMC are of the 4 bay configuration. There are two versions of the drawings. One is the as built composite side, and the other is the rebuilt steel side.

Subject: [STMFC] LV Hoppers
In my ongoing research and attempt to model the various cars shown in one particular wayfreight I've encountered what I believe will be the single most challenging modeling project of the bunch - one of the Lehigh Valley's six-ribbed, 2 bay hoppers (LV series 42000-42950). These cars were rebuilt from quad hoppers.
I know the Hobbyline/Lionel quad hopper was based on these cars. My understanding is there were drawings of the car (in their 4-bay configuration?) published in the August 1997 issue of RMC.
