The old Athearn Blue Box cars had major coupler height issues (too low). Shimming the trucks was your only option.
The later Athearn Blue Box (and current RTR) 50' FMC Box cars have their couplers too high (they are at the correct height with the McHenrys, but if you convert to kadees they will be too high). All you need to do with those is take the coupler box out, flip it upside down, put in the kadee, and mount it back on the car.
MDC/Roundhouse cars always has their coupler height too low. Converting those cars to metal wheels is also a pain. If the car prototypically has 36" wheels, the car will be tooled for them, but will come with 33" plastic wheels. If you put in 36" wheels, and hte coupler height is then correct, the flanges will catch on the underside details on the car. An example of that would be the 52'6" (they call it a 50') modern gondola. With their 50' box cars, they are a little better. The car still needs to be shimmed after the 36" wheels are on so you won't have any problems there.
Kadee makes a coupler for anything and everything. If all else fails, glue a kadee coupler box onto the car
