Are these alum. slots American Racing Wheels?

[66FBCharger]

I have these aluminum slots. Two of them are "unilug" and two use the shank style lug nuts. They have American Racing Wheels center caps (two different styles). I assume they are American racing wheels but would like to know if they are or are a knock off with American racing wheel centers.
Where do I find the correct lug nuts and washers for the "unilug" wheels?

Kind of looks like Ansens or maybe ET's with the unilug, but "I'm not positive", the old slots were all, so much alike... Here are some Westerns on some one elses car...
