I got mine from the local EV club guys who salvage parts from whatever they find. I would imagine you could find them on ebay quite easily. The one thing you must know is what mV drop the gauge is designed to use, and then you must get a matching shunt. Most are 50, 75, or 100mV drop shunts.

Here are a few auctions:

Ammeter:
Rectangle White Plastic Housing DC 0-200A Range Ammeter | eBay

Shunt:
Shunt Resistor for DC 200A 75mV Current Meter Ammeter | eBay

Ammeter and shunt with a digital display (nice because bumps throw the analog one all over the place).
