SS37Jag

Hey all, new to forum but looking for any info/resources of the solex 35 faie carb. Might have to try and find a replacement if I cant rebuild this one. I inherited this car recently and he was working on carb last time he was able to work on it. Does anyone know if there is a reliable place to purchase one of these if available or any that would be similar fit? It is almost completely original and trying to keep it that way. Thanks for any help you can give me. Jamie
