Make your own, its not that difficult with a drill, angle grinder and a file or die grinder.

A small friendly shop next to me was also thinking about producing the complete exhaust for the 924, i even posted an offer but since nobody was interested they dropped the idea and did a lot of VW stuff instead

Isn't there a local steel company, black smiting etc? Maybe someone that do water or laser cutting, that can do the entire job of cutting a flange?
Just a quick google and you can get steel plate bar from amazon.se https://www.amazon.se/Platt-st%C3%A5l-plattj%C3%A4rn-2000-l%C3%A5ngt/dp/B07GNLPP3N/ref=sr_1_2?dchild=1&keywords=plattj%C3%A4rn%2B12mm&qid=1613720634&sr=8-2&th=1
I'm sure Amazon or ebay ship to Finland too.
Can you read swedish? If not try do google translate this: http://ajden.se/ajden/flansar/index.htm
He makes custom flanges etc, If he hasn't got a CAD for it he can make one from a gasket.
At least he used to, send him a mail.

I have been regarding wastegate flanges as an option since they are close to the right size for the turbo head. Not sure on the NA specs as I am new. A lot of elbow grease with a file or a little time on a milling machine and four of these should be perfect if you're up to using separate flanges:

VW flanges are a very close option from what I've researched but I don't have any measurements.
