Bought this cobra need help identifying its origin

[Carmotive]

I recently acquired a replica cobra with very little history. It is missing the decal from the company that built it. There has many characteristics that make it unique. I am hoping someone here can help me identify where it was built. It seems to be a early 80s build. It has a 427 with Weber 8 stack. Custom billet air cleaners. Brass inserts in the valve covers. Brass bumpers. Brass shift bezel. The gauges are from classic instruments with brass bezels. Chrome spoke knock off wheels. Electric Brake vacuum pump. Side pipes that are removable with one Alan bolt. It seems to be built extremely well and designed to actually be raced, not just a conversation piece or Sunday cruiser. It has a 8 digit assigned Arizona vin number. Any help is appreciated. I have attached as many pictures as allowed.
