Where to get new front disc for my -67 Barracuda

Thanks for your help, I will open one side and check those measures. You know, from here in Finland those are difficult to get, I have rebuild almost whole car and I need to use your help, who got parts near by. I just finaliced swap of rear differential, I have now Yokon mounted. Waiting for better road conditions, we still have some snow on the roads, damn...

How about brake shoes, do you have info for those?
