Where to buy replacement tuner for Petrucci BFR?

I am outside the US and have a Petrucci BFR 6 String from around 2009 I believe.

The D string tuner has developed some play in the tuning peg so it appears to slip a bit in either direction before applying torque when trying to tune the string.

The tuner has a pearl head. Think I need a replacement tuner, but I am not sure of the exact model part or where to buy a replacement to be shipped outside the US.

Any help?

Thank you!
