Great part, but don't be one of those people who expects a new part to match every 50 year old guitar perfectly.
It was perfect for me and my guitar but not all of the mounting holes lined up exactly. My guitar isn't pristine and I also trimmed my guard to take new pickups and bridge so I can use it onstage so it didn't matter to me. Since Harmony did things by hand back in the 60's it probably won't match your mounting holes exactly either. The bridge holes did line up perfectly which is the critical part. If you want the mounting holes to line up perfectly you would have to get one without holes and locate and drill the holes yourself or get a guitar repairman to do it for you.
