How to identify brand of front disk/calipers ?

[Racer57]

I bought my Cuda with front disk brakes. I know they were added at some point in the past. How do I find out if they are factory or some other brand ?

Usually by appearance, maybe post a picture and we can help you out

Factory calipers would be manufactured by Kelsey Hayes and look like one of these.  KH80012 for 1970 models and I "believe" that the 1971 through 1974 models would have come with KH86166 casting number.  Maybe someone else can confirm that.
