What thread are the little alignment bolts in my rear dropouts?
It's an MB (Dronfield) frame, 753, Campag dropouts I think.
I presume they're metric... M3 perhaps? Any ideas on a replacement - one of mine is bent and the other is missing...
M3 would appear to be the case:

These are actually some of the best-value ones I've seen on t'internet; in this age of vertical dropouts on new-build bikes they seem increasingly harder - and dearer - to come by. Genuine Campag ones go for silly prices on eBay (20-odd quid a set at times!!).
