Well if you’re that particular about it... I have to ask what you’re going to be selling, because I want to buy my vintage bike from you.
Size 18” MTB sizing. Never ridden a road bike more than 2 circles in a parking lot.
You’re probably a good enough mechanic to know this already, but maybe drill and tap. When you’re done with the experiment screw a grub screw into the hole flush, putty, sand, and paint over?
