2000 996 C4 guage cluster bulbs?

[mikesz]

I am in the process of swapping a 2000 996 gauge cluster from a C4 into my 99 Boxster. Yes I know the gas gauge will be off. I want to replace the bulbs that light up the gauges there is one out in the tach and if I replace one I might as well replace them all. the faces are a silver and lightbulbs are amber and want to keep it that way. Can someone point me as to where I can find quality replacement bulbs at a reasonable price. I have only been able to find clear bulbs.
