G3 - Missing keys

[hardcastle]

Hey everyone, I'm knew here.

Anyway I'm getting stuck into using Macs at work so I figure I'd get out that Ibook G3 and get stuck into it, however this is where the issue arrives, I'm missing several keys from the keyboard.

So....

Is it possible to mount G4 keys on a G3 keyboard, I.E are the two keyboards more or less the same, in terms of key placement and fitting ?

If not, cheapest way of sourcing a replacable keyboard as a whole? Ebay I'm guessing..

Anyway,

thanks in advance,
