At the risk of sounding sarcastic they would be - 40 shells.
Mine is 1.7500" at standard, but it's a Reliant crank and I have a slight suspicion they were toleranced marginally differently from Austin ones. May be better to check with someone who sounds more confident.

Stuart sounds confident, looks like the right answer to me, 1.750" - .040" = 1.710".
Yes, the shells will be - .040".
