Power options on fender tag

I am looking at another '70 cuda and this car obviously has the engine swapped from 318 to 426. But, I'm very suspicious of numerous addons that are not on the fender tag. Shouldn't options like: Ralleye gauges, power windows, Rim-blow ... all be on the fender tag as separate number entries? What about bumper guards (small bumperettes)?
