Modeling BNSF and Milwaukee Road in SW Wisconsin
The question here is what exact year were the cars actually built?
The ACI system was discontinued in 1977.

The ACI label system(Kar-Trak') was started in 1967 and all cars were to be labeled by June of 1970. Most railroads found serious issues with the system and many of the wayside 'readers' never got installed. By Feb 1978 the program was stopped and there was no longer a need to apply the labels. Yhe DM&IR was one of the testing railroads(IIRC, the PRR was also a tester). They system work great on the DM&IR's ore hoppers. Issues not caught on the DM&IR tests were:
Your 1975 car should have them, but looking at pictures, I can see either faded areas or 'paint over' on many of the wood chip car photos that I have looked at. BN may have been very aggressive about removing the labels, or never put them on due to the cars being in local service.
If you are modeling the 70's - Yes they were on most cars, but many of the photos one finds on the Internet web sites are taken much later. One of the 'urban myths' one hears is that the railroads killed the project as the 'government' could see what they are doing! Of course, a few years later BN started testing what is now the AEI system(RFID technology).
