Current Projects chat and miscellany

I'm building up an old BSA i got for £30, bought one of these for it as it was a 3 speed to start with, and built it into a fresh rim -

Problem i've got is that the handlebars stem is 23.8mm clamp, and i can't find a pair of drops to fit it :/

I have an old pair of old drops from a Peugeot that may fit in
