From Allstate Carburetor and another Ebay Shop called superflowcarbs from the States. I tried to get the set screws here, but no way. Same with blanks which I can drill by myself.
I got an Email from AED.

Markus,
That is completely my mistake sir. The HO blocks do in fact use an 8/32 thread for the IFR, while our Pro-Series blocks use the 6/32 thread.
I can mail you some restrictors if you have a difficult time locating them. Again, my apologies on the mix-up. Please let me know if I can help.
Thanks so much sir & have a great day,
Jeff Harris
