Yamaha BB1600 machine heads

[Nightvision]

(First, sorry for my bad english)

Hello,
I am a happy owner of a beautiful vintage Yamaha BB1600 made in Korea.
I am really happens of the sounds that beauty are able to, but machine heads are crap, they don"t do the job...

So, I would like to change it but I have no idea of what can I choose of remplacement.
It's vintage style with 3 holes...

Do you know what tuners/machine heads can fits ???

Here is a pic:




Thanks a lot

Those could be hard to find. They are probably Gotoh tuners made for Yamaha. If they really need to be replaced you may have to use another type of tuner (hipshot maybe?) and have the holes filled. Since those are not a standard tuner they will be hard to find.

Does anyone know which Hipshot Extender would work for this? I imagine the GB5 is closest, but the holes are still different.
