Default 1973 front master cylinder diameter?

I can't seem to find the correct diameter for a front master cylinder that works with a 1973 FLH front banana caliper. I thought it was 3/4" for years but
had a shop tell me 11/16?

Can someone tell me which is correct?

Thank you,
Gregg

3/4 is the correct size early bike - that guy works on cookie cutter bikes

It's 11/16 " --- you will NOT get a 3/4 " dia. reamer into the bore of the cyl
