Cross drilled & slotted rotors question.

[Spider Man]

I've been asking around and can't find any in Australia, only slotted and dimpled, to go on the 1972 spider.

A shop in the US has them, but what I'm not sure on will they fit on the car I have..
Has any one else fitted any?
Did you get them locally?
Did Alfa supply different specs to different countries?
Apparently (according to Alfa) my white Spider was delivered to Japan before calling Australia home (it does have an Aus compliance plate "shrug")

I only have reservations because I know I have gotten rotors before from America for a Jap car in the past and they didn't fit. (Same physical size but the bearings in the rear hubs didn't fit).
Thanks..

Just received some drawings of the rotors from the US..





Does that look like the ones we have?
I'm not with the car ATM wont be for 2 weeks, was hoping to order them and have them delivered for when I get home.
Cheers..
