Stamping an engine # (need skyhawk example)

[Fletch]

Hey,

Can someone give me an example of the engine number from a skyhawk? I took off my tags and now I've decided to get plates for the bikes and need to stamp my own #. I just need to know the format so I can make up a number and know what stamps I need to buy. I tried zooming in on the Grubee site, but no luck

Thanks
