Hardtop Identification Help

I bought an 81 cj5 recently and this hardtop came with it. Its a fiberglass top i think with aluminum rear swing out windows and aluminum door with sliding windows. I am hoping someone can help me identify who made this. I am passenger wing that goes in front of door but i think i can make one. I am trying to figure out how exactly it attaches at the windshield. I have some pieces that dont seem to fit properly at the windshield. They may be wrong pieces i dont know. Thank you

Edit. The top appears to be aluminum instead of fiberglass. I scratched a place to shiny metal and a magnet wouldn't stick to it
