EC Carburetors (dot com) has a wide variety of radiused and non-radiused filter adapters, if that's an appealing option. I got one from them to use on my Mac small flat back carb, and it fits well. I had to look at the specs for one after the other online till I found one that matched my needs. Might be easier to phone them with info on which carb you have?
