ironbird

A couple of days ago I received this Ironbird in great condition. It's an IB-657, which I've only found in the 1992 catalog. It arrived with the original tag and synthetic leather bag. It plays great, electronics are clean and the neck is straight and nice. I will probably gig with it already...

My buddy is looking to buy an 80s era IronBird but it has a beat bridge, no nut and missing tuning machines. I was wondering if anyone knew the specs for the bridge size and the tuning peg diameter so I could find replacement parts for him? Thanks :)
