Like other long legged and short torso-d people who ride vintage bikes, I'm somewhat forced to ride smaller bikes. Hate it, to be honest, trying to find a road bike with a 59cm seat tube and 55cm top tube is, uh, dang near impossible. I make a ~55cm square frame work with a 80mm stem slightly higher than traditional and a compact handlebar. It is a touch squirrelly compared to when using a 100mm stem and traditional drops, but it works.
