Just a quick warning: I realized something.
Obviously that's not the stock MAFAC part. That means the bolt may not have the same specs as the MAFAC part. So just be aware, while I can tell you what the MAFAC part uses, you don't have the MAFAC part. Because the part was from Greece, was can be 95% sure it'll be Metric, so it'll use a metric bolt. We can hope it's 6mm and same thread pitch. But ... you may get the bolts from Amazon and they don't fit. Fortunately, Amazon offers easy returns.
And no - that bolt is not supposed to contact the bridge. Think about it - the top-down longer bolt goes straight through the bridge. Ain't moving anywhere with that config.
