Many 240 have identical Jets/needles. Diaphragms are all the same so 1 could be rebuilt and made to suit your application.
Added note. Not all Stromberg CD175s were made for Volvos, so be aware some won't work at all, especially if they are made to fit the wrong side.
The tag on the top of the carb has numbers pertaining to the model, jet and needle size check that against the list.
The ebay sell wants £199 for a piece of scrap.
I just noted listed as "new carb"!!!!
